fun fact: Michael Cera asked Rihanna if he could slap her ass for real and she said “you can slap my ass for real if I can slap you in the face for real” and he was like alright. and they did the take like 3 times and Michael was like “you’re not hitting me hard enough do it for real” and then she slapped the fuck out of him and threw off his equilibrium so much he had to go lay down in his trailer for like half an hour lmao and that’s the take they used in the movie with no added sound effects
all of that aside
“you can slap my ass for real if I can slap you in the face for real”
is the best answer ever.
