Civil Protection/Funny

"Mike: Yeah, it was looking pretty bad... But then!: (transition to alien invasion) Aliens from outer space showed up and started attacking the earth. (Beat) They decimated our defenses in a matter of hours, forcing us to surrender (transitions to conveyor belt with dead people on it and a giant line of people enslaved by combine soldiers) and the aftermath left 80% of the population dead, and the rest of humanity conquered on its own planet! And suddenly, it's like, boom, problem solved. Dave: I'll give you that. Killing off five billion people did wonders for most of our social problems.

 * Mike and Dave meeting a strider (in case you don't know, it is a giant alien-cyborg hybrid tripod creature armed with a giant laser cannon)

"Mike: Batman can afford to go around all night throwing ninja stars at people! Because he doesn't have to go work in the morning! Superman has to go to work, Spider-Man has to go to work, not Batman! He gets to sleep in in the morning, and he has a butler!"
 * Mike's rant on Batman:

"Mike: If you go trick or treating, great. But if someone answers the door naked, please call us immediately. You may think they're just playing a joke or acting a little weird, but no. It never amounts to anything good. We find it's usually just the tip of the iceberg with these people. Dave: Oh, man, like the Arbuckle residence, where we found all those dead-
