Host Alex Trebek asked the contestants which "Australian hip-hopper used the pet name/street name system to come up with her rap name." Nicholas Berube buzzed in, only to incorrectly drop the "Chasing Time" MC's name, an error that cost him $1,600.
To be fair, my answer probably would have been "looooooooool did you just say 'hip-hopper,'" so I can't be too harsh.
Besides, Nicholas swears he's a Banks fan. He tweeted an apology for the mix-up on January 20.
