Gumball Trees

Princess: Oh no!!! When I took a sip of my drink, it made me swallow my gum!
Dad: Hmmmm, Mom, should we rush her to the emergency room?
Mom: Eh, let's wait to see if the gumball tree starts growing first.
Dad: What flavor of gum was it so we know what to look for?
Princess: Blueberry.

Later, at bedtime Dad kisses her cheek good-night.
Dad: Mmmmm, you taste a little like blueberry.
Princess (with nervous disbelief): Oh, Daddy!

Half hour after being put to bed:
Princess: I need a drink of water.
Dad: That'll make the gum get hard.
Mom: You know how water makes plants grow faster.
