It was Saturday night and Superman wanted to party.  He flew over to
Wonder Woman's house to see what was going on over there.  Landing on
her balcony, he looked in her bedroom window and saw her lying in bed
naked.  "Hey," he thought to himself, "I'm faster than a speeding
bullet.  I'll fly in there, have sex with her and be gone before she
knows it!"  He does it but something startles Wonder Woman and she says,
"Did you hear something?"  "No," replied the Invisible Man, "but my
rear end is killing me."   Lyle's Joke Boutique.
