The Watch

After a security guard is murdered in his store, Costco manager Evan (Ben Stiller) vows to catch the killer. When he receives no help from the lazy local cops, he starts a neighborhood watch. At first, no one takes them seriously. Then they stumble across a glowing silver orb that has the power to blow shit up. After responding to a call, they discover an alien at the crime scene, and suddenly the fate of the world is in the hands of this unlikely group of heroes. Most of The Watch's jokes are crude and kinda immature. Still, it's the best movie with aliens and dick jokes since Paul.
