ST. LOUIS (Aug. 28) - Crazy carp have invaded Missouri's rivers. Two species of nonnative carp have been jumping into boats, injuring occupants and damaging the watercraft.

A state fisheries biologist motoring near Columbia had a filling knocked out of his tooth by a high-flying fish that struck him on the side of the head. Another state biologist in the St. Charles area was seriously hurt when he was hit by a giant carp.

You gotta love this state with its crazy fish.
