Make up a limerick (a little goofy poem) with your sibling or parent — you each come up with every other line. It doesn't necessarily have to make sense. Here's an example:
There once was a boy named Bill.
He liked to eat burgers from the grill.
But sometimes he'd eat
Too close to the heat
And he'd drop his beef and then his dog would eat it up off of the ground — what a pill!
Traveler: I always seem to get sick the night before I leave on a trip.
Travel Agent: Then why don't you leave a day earlier?
