Alligator

Despite the heroic efforts of B-movie great Henry Silva who plays a fearless alligator hunter and Bart Braverman who plays an intrepid reporter, it takes Robert Forster's exploding a bomb in an L.A. sewer that finally does in the giant alligator (that happens to be the long lost pet of Forster's lover, whose Dad flushed it down the toilet ten years before!) But, never fear, another tiny alligator appears out of a sewer drainpipe before the credits roll...
Thanks, Evil Ed!
