Blonde joke:
A man is mowing his lawn, when he sees his blonde neighbor come outside, open her mailbox, get confused, shut the mailbox, then go back inside.
He watches her repeat this routine several times, with her obviously becoming more frustrated each time.
Against his better judgment, he finally stops her and asks, "I've noticed you going back and forth today, are you expecting something?"
"No," she sighs... "It's my stupid computer, it keeps saying 'you've got mail."
