Lawyer
A lawyer boarded an airplane in New Orleans with a box of frozen crabs and asked a blonde flight attendant to take care of them for him.
She took the box and promised to put it in the crew's refrigerator. He advised her that he was holding her personally responsible for them staying frozen, mentioning in a very haughty manner that he was a lawyer, and proceeded to rant at her about what would happen if she let them thaw out. Needless to say, she was annoyed by his behavior.
Shortly before landing in New York, she used the intercom to announce to the entire cabin, "Would the lawyer who gave me the crabs in New Orleans please raise your hand?"
Not one hand went up, so she took them home and ate them.
Two lessons here:
1. Lawyers aren't as smart as they think they are.
2. Blonds aren't as dumb as most folks think.
