fake being sick so you can stay home
break a bone
write a poem/story/song
be on TV/in a newspaper
dance on a bar or table
have a crazy haircut
ride a roller coaster
collect something as a hobby
drop your phone in the toilet
fall asleep in class/at work
dye your hair a crazy color
go camping in a tent
be in a fight with someone
cry while watching a movie
do something embarrassing in public
wake up still drunk the next day after the party
