Three balloons. Daddy balloon, mummy balloon and baby balloon.

Daddy balloon saids to baby balloon, look son, you are much to old to sleep with mummy and daddy, you will have to sleep in you're own bed. Baby balloon protests, I like sleeping with you and mummy. No you are not sleeping with us and thats final. Ok saids baby balloon sadly.

Two in the morning baby ballon wakes up and dicides to climb into beb with mummy and daddy. He finds there is no room, so he unties his dads knot and lets out some air, and ties him up again. Still no room, so he unties his mummys knot, also lets some air out and ties her up again. he still can't get in, so he unties his own knot, lets out some air, and ties himself up again, he finally has room, and snuggles down with mummy and daddy.

The next day they all wake, and daddy balloon is really angry. He said son, I am really disapointed with you, I said you can't sleep with us. you've let me down, you're mummy down, and you're self down to.
