Giant Polish dockworker, Kraczewski, was considered by most of the longshoremen to be a great lover. They claimed he could make love to twenty girls in an hour. When some disbelieving seamen showed up, bets were made and the next night twenty girls were lined up in one of the warehouses.
The big Polack went to work. He had made love to the first dozen when suddenly he fell to the floor in a state of exhaustion. His pals rushed up to him screaming, “What happened?” “I dunno,” answered Kraczewaski. “I did okay this afternoon at the rehearsal!”
