Andy Samberg appeared on Late Night with Conan O’Brien last night, in support of Hot Rod, but the bulk of his time was actually devoted to an anecdote about he and his friend and cast mate, Jorma Taccone, convincing their Canadian union set driver to follow their lead and rub strong-scented peppermint oil on his balls (don’t ask, regarding the set-up). He allegedly did, and they snapped an amusing photo of him.

Samberg then poked mild, mock-cautionary fun at other big screen offerings going up against Hot Rod, saying that he’d heard if audiences went to see Underdog, their eyes would burn out of their head and their faces would melt, like in Indiana Jones and the Temple of Doom. He wasn’t done there, though. “It’s strange. Great movie, perfectly fine if you see it once, but I’ve heard that if you see The Simpsons Movie a second time, you get IBS. …And if you see The Bourne Ultimatum, you’ll get syphilis.”
