Rent Close Encounters of the Nerd Kind (2001)

Tim Maroon (Mark-Paul Gosselaarl) returns to his hometown of Eureka, California after losing his job as a TV weatherman in Los Angeles. He runs into two former 'no hope' classmates who are working in a fast food restaurant and arranges to go on a camping trip with them. As they get drunk sitting round a campfire, a flying saucer lands and an E.T like, two foot tall, wrinkled green alien appears with what seems to be a weapon. Fearing for their lives, they shoot the alien in the head with an arrow. It falls lifeless to the ground and the flying saucer takes off without it. They then hit on the great idea they can sell the aliens body and make enough money so they can all leave Eureka forever!
