Taking Care of Business (1990)

Plot hole: When Jimmy and Spencer are being chased by the cops at the stadium, Jimmy uses a credit card to jimmy a door knob latch. However, the knob isn't locked, because it has no key hole. The dead bolt above the door handle is the one locked, and no credit card is going to jimmy a deadbolt.

Plot hole: When Sakamoto prepares to deliver his final serve in the tennis match, he declares, "Triple set point." Later we learn that he lost in three straight sets, so the statement should have been, "Triple match point."
