Over at Lifehacker there is a discussion of really bad jokes. I laughed and laughed.
from Bakersdozen AfroWithaChanceofMeatballs
You are on a horse, galloping at a constant speed. On your right side is sharp drop off, and on your left side is an elephant traveling at the same speed as you. Directly in front of you is a galloping kangaroo and your horse is unable to overtake it. Behind you is a lion running at the same speed as you and the kangaroo. What must you do to safely get out of this highly dangerous situation?
Get off the merry-go-round—you’re drunk.
Lots of great animal jokes.
