Men are like computers: Hard to figure out and never have enough memory.
Why are all dumb blonde jokes one-liners?
So men can remember them.
Mother: "How was math today?"
Little Johnny: "Our teacher has a bad memory. For three days she asked us how much is two and two. We told her it was four. But she still doesn't know. Today she asked us again!"
Why is a man different from a computer?
You only have to tell the computer once.
Did you ever walk into a room and and forget why you walked in?
That's how dogs spend their lives.
