A marine biologist developed a race of genetically engineered dolphins that
could live forever if they were fed a steady diet of seagulls. One day his
supply of the birds ran out. So he had to go out and trap some more. On the
way back, he spied two lions asleep on the road. Afraid to wake them, he
gingerly stepped over them. Immediately, he was arrested and charged with
transporting gulls across sedate lions for immortal porpoises.
