Remo Williams: The Adventure Begins (1985) - racist and sexist Kung Fu Panda and not funny.
Grumpy Old Men (1993) - the grumpy old men were a bit funny. It was the female characters that I couldn't stand. Also, I don't need to watch this movie. I'll just watch Math Teacher turn into a grumpy old man in thirty years.
The Naked Gun 2 1/2: The Smell of Fear (1991) - I hung in there for ten minutes. Juvenile, childish humor. No part of it was funny in those ten minutes.
