Leo Anthony Gallagher (born July 24, 1947), known commonly by just his last name, is an American comedian and prop comic. Born in Fort Bragg, North Carolina, he is known for smashing watermelons, Jell-o, and sundry other items with a sledgehammer he has dubbed his "Sledge-o-matic". His popularity is largely based on live appearances on a number of television specials, where those in the front rows of the audience must protect themselves from flying produce with plastic sheeting.
Gallagher was a candidate for governor in the 2003 California recall election. He placed 16th in a field of 135 candidates (see Results of the 2003 California recall).
