In the park the other day, I passed a guy giving life support to a lady, who was lying half in and half out of a decorative pond. He was pumping her chest and water was gushing out from her mouth. In between pumping the guy said, "I'm trying to revive this lady. She must have fallen into the pond and lost consciousness. I've been pumping like this for over 5 minutes and water keeps pouring out from her mouth." I said to him, "If you don't take her bottom out of the water, you'll pump the pond dry."

Thanks Jethro.

Good one
