One last word...
You know,in the dinner when Brian says "Finally you two will have something in common besides me"...? Well, they do and that pisses Brian off really bad. He's not jealous of finding Michael and Justin in bed as a sexual thing, he's mad that they would rather work on a comic book than go out and get drunk and fuck around like him. Brian is afraid that Justin will find a "better orgasm" than he has with him *g* like Ben says.He's so afraid that he's no longer their hero...
That's why he urinates on the comic, he thinks it's not about him, that Michael and Justin have finally found something else to gravitate around of. Until Debbie reassures him that it's not the case. Then he apologizes...and he really means it!!YO! ;)
