One day a few years back, Kenan Thompson got a call at his home in New York City. When he picked up, he heard a voice on the other end of the line that was both familiar and distant at the same time. It was Kel Mitchells.

I was in my backyard, Thompson told HuffPost earlier this year . I havent talked to this dude in years. I wondered cause I heard the same rumors of beef and all that, so I didnt really know, since I hadnt spoken with him if there was really a problem or not.

During the second half of the 1990s, Thompson and Mitchell seemed almost inseparable on screen. They became one of comedys most famous duos, first on Nickelodeons sketch show All That and then with their own show, Kenan & Kel . And 20 years ago on Tuesday, they released the 1997 film Good Burger , a cult classic that remains close to the hearts of millions of millennials.
