it turns out that thinking of jokes is hard. really hard. the internet isn’t much help, either; it’s hard to be funny when you’re trying to be funny.
it becomes much, much easier to make bucky laugh when sam discovers that he’s ticklish.
(he and sam chase each other around the house, yelling incoherently, for fully fifteen minutes before bucky lets sam pin him to the couch and tickle him until he cries from laughing so hard)
