Bait

Guy goes on a fishing trip. While loading up his boat he sees another fisherman walk up the bank with a stringer of fish. After much pleading as to the secret of his success the angler told him he was a doctor. His specialty left a nice supply of infected tonsils which seemed to work well for fish bait. Soon another man appeared with a stringer of bigger fish. The poor guy has to know and soon finds out it is another doctor who specializes in appendectomies leaving a supply of bait. Just as the guy is ready to leave he spots another angler with a bigger stringer of huge fish. When he asked the man what kind of doctor he was he replied "Doctor? I'm no doctor I'm a Rabbi"..
