I've found these jokes on the web
Two Balloons
Two balloons were floating across the desert.
One balloon said to the other:
"Look out for the cactussssssssssss!"
God and the man
A man visits God and says "God, do you mind if I ask you a
few questions?" God says "No, ask me anything at all."
So the man says "God, you've been around for a very long time,
so, for you, how long is a thousand years?"
God replies "For me, a thousand years is only five minutes."
The man then says "That's interesting God. And, for you,
how much is a million dollars?"
God replies "For me, a million dollars is only five cents."
The man says "Really? Well then God, could you lend me
five cents please?"
God looks at the man, smiles, and says "Of course my son.
Just wait five minutes!"
Worms
It was the first day of Biology for a group of teenagers. The
professor had arranged a short demonstration for the class.
He took a worm and dropped it into a glass of water. The worm
wriggled about in the water.
Then he took a second worm and dropped it into a glass of alcohol.
The worm immediately died.
The professor asked the students if anyone knew what the point of
the demonstration was.
A boy raised his hand and said, "You're showing us that if we drink
alcohol, we won't have worms."
