Rock, Esquire's Summer cover star, sat down for a new episode of "Explain This," where celebrities run down moments from their careers. When we showed Rock a picture of himself and Sandler from 2018's The Week Of, he launched into two incredible stories about Sandler. (Followed by a half dozen compliments.) In the first story, Rock remembered the first time he saw Sandler perform stand-up. It was at New York's legendary Comic Strip Live, where comedians like Rock and Sandler worked their way into the public eye. Rock says it took a year or two to perform at the club on a weekend night. One time, Rock took a week-long trip to Los Angeles—and when he came back, here was this guy Sandler, coming out of nowhere, hamming it up on a weekend night at the club.
