Two fishermen from Minnesota sit on the beach of the lake and watching girl riding on water skis. Suddenly the rope breaks, she falls and doesn't float.
Fishermen swim, dive, pull out her, and start doing artificial respiration... Nothing happens.
Half an hour later, one fisherman says to another:
- Listen, but she was skiing?
- Yes, skiing!
- But this one is on skates!

A Good Samaritan will always wait for the right opportunity.
