The hugely popular sitcom, A Different World, was set in a fictitious, historically black university. With real-life enrollment numbers down today and student debt high, HBCUs are feeling the pinch. The all-star cast of that show, which is still in syndication, hit the road to help. Here's ABC's Ashton sing.

It's a different world. It's a different world. Where you come from.

Will you have me, Dwyane, as your lawfully wedded husband from this day forth to having a hole in richer for Poora? Baby, please, please.

Please. I do.

Now, nearly 40 years after that classic episode and many others, the cast of A Different World back together for a reunion tour of historically black colleges and universities.

They need to know that we're watching you and we're rooting for you because it's very hard on this generation to go to school and finish school financially in other ways. And I feel we're the natural ambassadors for the HBCU community. Yeah, and to get them to go.

Already making stops at Clark Atlanta University, Spelman, Morehouse, and Howard University, looking to raise awareness, enrollments, and scholarship funds. It comes at a critical time for HBCUs, with some facing funding gaps, and graduates hit hard by student loan debt. What was that moment where you said, We got to get the band back together?

It's It's really simple. A Different World has never been off the air since it premiered in 1987. We've been fortunate that we've all been ambassadors for HBCUs, and the idea that if we would come and go back and talk about the show and why not only people who watched it in prime time, but why their children now and their grandchildren watch it, why all these future generations are still finding the evergreen subjects that we talk about relevant today.

That tour also taking them to the White House for a meeting with Vice President Kamala Harris.

Welcome to the Vice President's office. I am proudly the first graduate of the H. B. Ever occupied this.

Come on. With a briefing on the artworks in her office.

Thurgood Marshall, and the artist Fontaineau is actually a Howard graduate. Hi. I keep Thurgood over my right shoulder. Yes.

And Press Secretary, Carine Jean-Pierre, leading a rendition of the iconic theme song.

It's a different world.

A Different World, Now in Syndication, was a spinoff from The Cosby Show. Lisa Bonet's character, Denise Huxable, left home for Home in College, a fictional HBCU in Virginia.

I'm just sorry, I couldn't find a wheelchair. A wheelchair? If you put one in the back seat of your car, it's about the only way you can find a place to park that's not in the boonies.

Willy, that's terrible. The series, aired for six seasons, from 1987 to 1993, and is widely credited with boosting enrollments at HBCUs, and also showing the richness and diversity of Black culture. What's it like for you guys sitting up there and getting these questions from these students who were not born when a different world was on the air.

The issues that we were dealing with then, we're still dealing with in some way, shape, or form today. They watched us navigate certain concepts and realities, and they are inspired.

Also, what you have to understand is that what was brilliant about the show was that imparting all of this wonderful information and dealing with all of these topics of importance That fun was never absent from our storytelling.

These scarcans are delicious.

The Groundbreaking series, tackling topics like AIDS.

By the following spring, Josie Webb had died of acquired immune deficiency syndrome, disease we all know as AIDS.

Racism.

My grandfather built this country, man. He fought wars for it. In most places he went, wouldn't let him sit down and get a cup of coffee.

And classism.

I mean, imagine coming from an African-American family that owned over 100 slaves.

The show, introducing America to Jada Pinkett-Smith and future Oscar winners Halle Berry and Marissa Tomei. Let them go. Come on, baby. You know I'm fragile. Legendary rapper Tupac Shakur, even making a guest appearance.

Use my first love when I can't get five minutes alone with you.

Kadeem Hardison directed the Tupac episode, saying his potential was obvious.

I can't reach that place that he can get to. I don't even know that place.

Establish stars like Diane Carroll, Whoopie Goldberg, Lena Horne, Patti LaBelle, and Billy D. Williams also visiting Hillman.

This is indeed a very auspicious occasion. Very, very suspicious.

The reunion tour also giving the still close-knit cast an opportunity to hang out together.

It's just a real family affair. So the truth is, yes, it's an opportunity to work, but it's also just an opportunity to hang out with people that you really love.

Sharing some backstage secrets. How producer and director Debbie Allen, a Howard grad, added her own secret sauce to the show.

She walked into the pit and saw salt and pepper and ketchup. She was like, Where's your hot sauce? So she put hot sauce in the world. All the tables. Yes. I will.

Their take on the now iconic moment where Dwyane Wayne interrupts Whitley's wedding.

Whitley, I love you. And if you'll have me, I want you to be my wife. What the hell are you doing? I'm sorry, Byron. I love her. I wasn't I'm not against us getting married. I just was against breaking up that man's wedding who I supported through his campaign. I just thought, Come on, we love this dude. Why are we going to turn him into this heel? You know what I mean? What guy When a guy does that? He has to be really in love.

The actors, soaking in all the love from fans. It's really like a retroactive love affair. It's beautiful for us at this age to get all this appreciation. It's quite humbling, actually.

We are receiving our flowers now in ways that it never happened before.

I know everybody seeing you guys all together has got super fans excited. Is there any hint? Maybe on-screen reunion for a different world?

For years, I've said never.

Now I just say, never say never.

I would like to see where these characters are in their 50s and so would I, because that's another change of life.

Our thanks to Ashan.
