9. Justin Bieber with Brazil's Sabrina Sato

Brazilian comedienne Sabrina Sato's act is entirely situational... and oh so awkward. Sato doesn't speak English, but she still gets major celebrity interviews thrown her way, like this sit-down with Canadian pop phenom Justin Bieber in 2010. After patiently listening to Sato struggle her way through a few questions she obviously didn't understand, Justin eventually suggested that Sabrina's companion read the questions ("Cause I never understand what you say"). Deleted footage from the interview reveals that at some point, Justin faked being asleep. Then he made a terrible scratch 'n' sniff joke.
