Even Evil Has Standards: In "The Cruise" Kevin is clearly afraid of the Widow Coulson because he believes she is much more crazier than him, even Allen agrees with Kevin and can be seen by her as well.
There are times when Kevin thinks that Pete Wilcox is even crazier than him.
Kevin actually gets turned off by the sociopathic behavior of his love interest Shauna, he even displays shock over the fact that Shauna has murdered her own mother as he never took a life before.

Hidden Depths: Kevin himself may be a drunken sociopath, but one of his most sincere wants is to be popular...and to have a hat with a weapon on it.
Silent Bob: Kevin "speaks", and the other characters react to what he "says", but the audience never hears it. Instead, the narrator tells us what Kevin "said". The only times Kevin actually verbally speaks are either in hallucinations and dreams, and in one episode where he told someone else to "fuck off".
Prison Rape: Percy has been sodomized in prison several times, and it's played for laughs.

Berserk Button: Percy and Anastasia both get extremely pissed off whenever they find out that they've been cheated on by the other one. Anastasia also gets really hot under the collar whenever people are really rude to her and don't speak to her like a "fucking lady".
Not-So-Imaginary Friend: A couple of episodes imply that Allan is some sort of spirit/demon entity that simply lives in Kevin's head. When Kevin temporarily dies from a heart attack, Allan returns to the "Imaginary Friends Galactic Headquarters" to be reassigned, while in another he becomes fed up with Kevin and tries to find another head to live in, interacting with several other characters.
