Eh, they're all pretty annoying, in my opinion. Towelie's character is only written around wanting to get high, while Sheila's protesting personality has been toned down she can still be annoying, Randy constantly hogging the spotlight and how he's derailed as a character is daunting, Bebe isn't really much of a character tbh as her defining trait is that she's a girl, I actually don't really find Dr. Mephesto all that annoying not gonna lie, and Kyle Schwartz is AWFUL, his character is just a stereotype, and I hate characters who's only defined by only one character trait, let alone ones who are defined by a stereotype.
