The 2nd best movie starring Roddy Piper. Hilarious, awesome, ridiculous movie.

Roddy Piper plays Sam Hell, who is captured and forced to wear metal underwear with a bomb in it. This explosive chastity panty features a dong flap to allow him to breed with fertile ladies, which is the mission he was captured to be used for. Frog men and other bad guys try to kill him, interfering with his sexual duties temporarily.
