I like when Ray is getting ready to fight (or to "go", "bub") and he lets out this massively high pitched phrase that sounds, to me, like "Comeon, jerk!". The jerk part of it is very clear, but the first word is extremely high pitched (even for Ray) and perhaps muffled or something as well. I'm sure you guys know what I mean...
As far as the kids, they don't really bother me. Except for Gloria, who is dorky and boring. Karen and Melody both have crushes on Jimmy, so they're cool with me. Pedro is such a sad little kid. No reason to hate him. Sheldon is what Mr. Hattrick says he is... a twerp. A total brat and a two-face ("your nobody now Jimmy" "Wanna be friends???"). But he's possibly the funniest character in the game. At least on my short list along with Ray, Lefty, Peanut, and Troy.
