Didn't know The Tonight Show had an open bar backstage? Neither did we, at least until director Quentin Tarantino made it abundantly clear during a 2003 appearance on the show. Tarantino was supposed to be promoting the premiere of Kill Bill but instead spent more time advertising the free drinks in the green room. After getting a whiff of Tarantino's breath, Leno called him out for having a few too many. Tarantino's defense? He was channeling actor Oliver Reed, who would reportedly drink before appearing on The Tonight Show during the Johnny Carson years. We're guessing this is one tradition Leno would have rather let die.
