I just watched Galaxy Quest with Ben. No matter how many times I watch this movie, it doesn't stop being funny.

My favourite quote is when they're landing on the alien planet, looking for berillym crystals, and they open the shuttle hatch, and the crewman extra goes crazy and says, "What are you doing? Is there air out there? You don't know!" To which the chief engineer (who is stoned the entire time) sniffs the air and says, "Seems okay to me."
