Six year old is pointing at a photo using his middle finger.
Dad: Don't use that finger to point.
Six Year Old: Why not.
Dad: Mom, you explain this one.
Mom: Its very bad manners to point a middle finger at someone. It means that you don't like them.
Six Year Old: Oh, I thought pointing your middle finger made the Easter Bunny fart.
Mom and Dad: uncontrollable laughter.
(Later found out that a seven year old told him that whopper.)
So next time you are driving down the road and give someone the bird, don't be surprised if you see a flatulent rabbit nearby.
