Dumb and Dumber

This might be the movie I have the strongest love/hate relationship with. I feel like I hate it, but then the cop says "Pull over!" and they go "No it's a cardigan but thanks for noticing", and how can I hate that?! I don't like the characters at all, but it makes me laugh so many times. It's so clever, and it's so stupid. It's so funny, and it's so annoying. What a dilemma.
