Sarah: Did Justin Bieber used to have a mohawk? 'cause his penis is so small.
Hannah: Yeah, mohawk-penis connection.
Corbin: I cut off my sidehawks and my balls grew back. Thank god.
Julia: Yeah, easier to suck them when they're bigger. Do you think my boobs are too small with this girl-hawk?
Corbin: Yes.
