I'm getting the distinct whiff of a certain Billy Bullshit Esq. from some of the stories being told here.
I don't think my stories sounded implausible at all, if you're referring to me. All that shit really happened. I tied someone's shoelaces together while he was outside wearing another pair of shoes and poured rotten milk all over his bed. I had gone to the cafeteria and gotten a couple little individual cartons of milk and let them sit outside all day. Is that really outside the realm of possibility? That's how we did things in the '80s!
Aside from the fact that it sounds like a montage from a John Hughes flick, no. I was referring more to some of the tales of retribution in the form of courageously thrown fists and bullies witrh tails between their legs, things that sound like retconned fantasies that serve as better endings than, y'know, "he bullied me for another 2 terms, it finally ended when I went to college".
