The balloon joke?
Tired of baby balloon creeping into their bed every night,
"Tonight you must stay in your own bed" said mummy.
When he was sure his mummy and daddy were asleep baby balloon crept into their room and tried to squeeze into their bed.
But try as he might he just couldn't fit in, so he undid the bottom of his mummy and let tiny bit air out of her. But to his dismay he still coultn't fit in, so he crept round to his daddy's side of the bed and undid his daddy's knot and let a little bit of air out. Again he tried to squeeze in but still couldn't quite fit. So he undid hiself and let a little bit of air out. Then he fitted in nice and snuggly and fell sound asleep.
When his mum woke up she was furious!
"Get into your own room at once and think of what you have done young man!" she shouted
"I am so dissappointed in you! Not only have you let me down and your father down, you''ve let yourself down too!"
