Man overboard drill.

The crew of a fast frigate was practising the man overboard drill by "rescuing" a bright orange fluorescent dummy dubbed Oscar. The captain watched as a young lieutenant nervously stopped the ship, turned it and maneuvered into place. Unfortunately, he ran right over Oscar. Surveying the remains of Oscar scattered around the ship, the captain told the lieutenant, "Son, do me a favour. If I ever fall overboard, just drop anchor and I'll swim to you."
