Dolphins

A formula is invented that makes dolphins live forever. Unfortunately, one of 
its ingredients is crushed baby seagulls, so the animal activists prohibit its 
use. Seaworld had to prevent its employees from secretly giving it to the dolphins, 
so they kept a loose lion at the door to the dolphin tank at night. One night, 
an attendant, who thought it wrong to deprive the dolphins of their formula, 
slipped the lion a mickey. When it fell asleep, the attendant stepped over the lion 
into the dolphin room, bearing the magic formula--whereupon he was arrested for 
carrying young gulls across a staid lion for immortal porpoises.....
