Miles: Hell no! I think I'd rather be a human centipede between Biz Markie and Justin Bieber, thanks.
This single phrase alludes to multiple things. First, Human Centiped was a 2010 movie about a crazy doctor who sews 3 people together from ass to mouth.
Biz Markie is a world renowned rapper and comedian, among many other talents, and has always been something of a heavyset man.
Justin Bieber is a young teen Canadian singer who has become a global phenomenon. He is constantly plagued with gay rumors.
