Funnyman Michael Cera dropped by the Late Show with David Letterman on Monday and revealed how he pranked the audience at a Sundance Film Festival Q&A in 2013.
While at the festival promoting his movie Crystal Fairy & the Magical Cactus, Cera asked a friend in the crowd to ask two specific questions during the Q&A. “The first part is when is the last time you saw your son Amos, and the second part is if you’re so sure he’s not your son why won’t you take the DNA test?” Cera explained.
According to Cera, the audience went silent and he responded by asking that the fans stick to questions about the movie. Letterman joked that Cera should be “banned for life” from Sundance after pulling that prank.
