"So bad it's good/funny" movies?

[KManX89]

What are some movies that are "so bad it's good/funny" to you? Movies that are so bad they bring some unintentional laughs?

I think I know one you're all gonna say right off the bat, but any others?

• The Room-Nuf 'sed.
• House of the Dead (in spots)-I don't want to give it TOO much credit for being "so bad it's good", but there are some LOL moments surrounding all the dreck in this movie for all the wrong reasons, like petrified teenagers suddenly becoming kung-fu masters when approaching the graveyard zombies with randomly-inserted game clips and this infamous line, though the rest of the movie is so bad, it's just painful to sit through, hence "in spots".
• The Happening-Mainly the infamous "What? No!" line. I every time at that part.
