Chris Rock has a plethora of today’s top comedians in his film “Top Five,” including Brian Regan! The comedian recently appeared on “The Late Show with David Letterman” and during his interview, he introduced a clip featuring his Sirius Radio producer character and Rock’s character Andre.

In the clip, Andre is recording a bumper for Sirius XM, but Regan’s character asks him to put some “stank” on it. Of course, Andre doesn’t know what that means. If you want to see what kind of “stank” is required to record a simple bumper, watch the clip below.

“Top Five” is written and directed by Rock as well as starring Rock along with a huge cast of stars, including Rosario Dawson, Kevin Hart, Whoopi Goldberg, Adam Sandler, Jerry Seinfeld, Romany Malco, Hayley Marie Norman, Ben Vereen, J.B. Smoove, Cedric the Entertainer and Ben Vereen.

Here’s what you can expect from “Top Five”:

“Pulsing with the rhythm of his greatest stand-up, Chris Rock’s TOP FIVE takes things to the next level, reveling in the high and the low, and blending a star-studded comedic romp with an irresistible romance. TOP FIVE digs under the surface of show business, politics, rap, and the exigencies of being black and famous today—holding it all up to the light in the way only Chris Rock can. Mingling echoes of Woody Allen and Dick Gregory with the energy of Kanye West and Jay Z, TOP FIVE is an original and radically new kind of American movie. Written, directed by, and starring Chris Rock, TOP FIVE tells the story of New York City comedian-turned-film star Andre Allen, whose unexpected encounter with a journalist (Rosario Dawson) forces him to confront the comedy career—and the past—that he’s left behind.”
