Cow Joke

Sometime during the night, I had this dream that my wife came home from work and announced that she had heard the funniest joke earlier in the day. "Let's hear it," I said.

"What kind of cow jumped over the moon?" she asked. I thought for moment and said, "I dunno." Hardly able to contain herself, she spilled forth the punchline, "A Gnatless Cow!" We laughed 'til we cried... and then I woke up.

Some jokes work great in dreams but just don't translate well to the real world.
