Lao hu tian ji (1978)

Multi-Hand Chick asks Crazy Frog for protection after stealing someone’s wallet at the casino. Foolishly he accepts, and even more foolishly he follows her home and removes his Invincible Armor when she pretends to be willing to sleep with him. Of course she steals it, and when he tries to follow her, he’s stopped by Dirty Tiger who is on a mission to bring Crazy Frog back to his wife. However, Dirty Tiger would really like to have that armor himself…
