I think I've had it all (snorers, 10 year old gremlins playing police to the delight if their parents, laugher, etc) but weirdly enough the most annoying one was probably the DYKWIA trying to pull his pretty young neighbour by detailing his (supposed?) life complete with figures contract, pay, value of the car etc) and heroic record (Obama asked him for business advice and he saved the life of two children because he's such an excellent swimmer) in an equally loud and obnoxious manner. Trying to rival with his mythomania, I myself started dreaming that I was James Bond and could push a button that would action his eject seat.
