“joking and laughing as they headed off to their new life”
“Life's a joke, so laugh while it's still funny.”
“I'll laugh until my head comes off".”
“Somebody cracks a joke, a whole row laughs, one witticism sets off another, and, like matches, they flare up and burn down.”
“Hey, that's life, flick it off if you can't take a joke.”
“If you tell a joke in the forest, but nobody laughs, was it a joke?”
