Several members of the house have almost gotten arrested several times, luckily the others were there to bail them out.
Toriel and Asgore have perfect records, Asriel and Frisk toilet-papered someone's house and almost got caught, Chara stabbed someone, Papyrus went out drinking despite being underage, woke up with a hangover and hasn't touched alcohol since, Undyne beat up a mailman, and Alphys almost got framed for stealing from a jewelry shop.
