In a sitcom like this where humour is the main export, you do still get a couple.
In Season 1, Jake's method for dealing with bullying: Make friends with the biggest guy in the class and get him to beat up the bully in the bathroom.
When Angela is revealed to have insulted the kids during the wedding (series 2, episode 1), Sue kicks her hard up the backside.
A joint one for Ben and for Pete in Series 3, Episode 2. In the episode where Ben runs around while playing chess, Pete's somewhat arrogant mother starts to note that Pete has almost never won anything against her. Pete gets Ben to challenge her at chess, and he promptly checkmates her in less than five moves. A Moment Of Awesome for Ben winning, and Pete's for reminding her to not be so arrogant.
Pete's friend Rick gets one when Jerkass tennis player Lance keeps stirring up a fuss and claiming that Karen is working against him. (To be fair, on one occasion she made a bad judgement but he made more than her). And that Ben is playing mind-games. When Lance says that he doesn't need to cheat to beat Rick and Pete, having played for his county, Rick is undeterred and simply asks "Which county was that then? Wankershire?"
After Karen is hit by a car in the finale of Series 3, Pete and Jake get a visit from the annoying anti-speedbump campaigner and verbal asskicking ensues shortly before Jake shuts the door in his face.
Pete (shortly after being asked if he is in favour of speedbumps): Let me see. I would say... given that my child is currently in hospital, having been hit by a speeding car, I would say on balance, erm, that my exact position is that in order to slow down all the shrivel-cocked Jeremy Clarkson wannabes, (gesturing at the campaigner) such as your good self, who seem to feel that any speed restriction is an abuse of their basic human right to drive like a pillock, I would be in favour of speed bumps. And, as a further traffic calming measure, I would also be in favour of rocket propelled grenades, targeted to disappear up their STUPID, COMPLACENT LITTLE ARSES!
Campaigner stands in shocked silence.
Pete: There, is that entirely clear for you?
The wife of Jerkass Norris calls him out at the Brockman's Christmas Party, promptly comes out in front of the entire room and walks off with her new partner.
