Do you take your kids on public transportation? If you do, a Bananaphone is invaluable. It’s just a banana, but once you say “Ring, ring! Ring, ring!” then it magically turns into a Bananaphone. You can use it to call Grandma, Grandpa, older sisters, Santa Claus, Daddy, really anyone. And after you’ve had enough conversation, you have a snack.
Of course, once you’ve eaten it, the game of Bananaphone is over. Unless, of course, you happen to have two bananas with you.
