Plot[ edit ] Ian Lafferty Josh Zuckerman is an year-old recent high school graduate. He searches for a girl online making it seem as if he is attractive and strong, although he is sweet and unassuming. He soon meets "Ms. Tasty" Katrina Bowden and agrees to meet her in person. She lives in Knoxville, Tennessee , while he lives in Chicago, Illinois. On the way to Knoxville, they come across a hitchhiker David Koechner , as the radiator in the Judge overheats. Felicia suggests urinating in the radiator in order to get to the next town, so they talk her into urinating into the radiator after her friends when the hitchhiker says he is empty.
They only works briefly as they try to leave the hitchhiker in the dust. The hitchhiker, frustrated at Ian's lack of concern for his well being, leaves, but not before urinating on the car window.
As Ian and Felicia wander to find help, Lance is waiting with the car as Ezekiel Seth Green happens to pass by in his horse-drawn buggy. Ezekiel and his Amish buddies repair the car while they join a Rumspringa party where Fall Out Boy are playing a concert, and at which Lance meets an attractive Amish girl, Mary Alice Greczyn.
The three promise to come again on the way back to do some work in return for fixing the car. They go to jail due to Ian throwing a tire iron into a state trooper car, due to his increasing frustration after trying to put a possum he hit out of its misery, and are released after Mary pays the bail. Upon arriving in Knoxville, they find a hotel that sports a wide variety of role playing rooms. Rex, who has discovered the Judge missing, arrives angrily and insists that they go back and that Ian cannot visit Ms.
After Ian pretends to be gay, Rex allows him to see Ms. Tasty, hoping this encounter will change Ian's mind. Ian finally meets Ms. However, when he tells her about Felicia, her seduction of Ian becomes a threat as her psychotic boyfriend Bobby Jo Dave Sheridan puts a gun to Ian's head. It becomes apparent that they work at a chop shop and attempt to steal the Judge. Lance and Mary arrive after having sex, as well as a redneck named Rick Michael Cudlitz whose girlfriend Brandy Andrea Anders slept with Lance earlier.
Felicia, however, is hiding in the car when Bobby Jo tries to steal it. Soon, a green car that has been continuously drag-racing with the Judge throughout the movie arrives. Ian manages to save Felicia, who then is able to run off and report to the police.
Young , two dim-witted self-declared "womanizers" from Ian's school, whom Ms. Tasty tried to manipulate into giving her the car. Bobby Jo is treated after being shot by Ian in self-defense. Felicia tells the police about the chop shop location and the couple is arrested. Upon finding out that if Mary leaves the Amish community, she will be shunned, Lance refuses to come back home and stays behind to marry Mary, while Ian and Felicia realize their love for each other.
Ian and Felicia drive to a tree where Ian throws his shoes up into the tree. A few weeks later Ian is Felicia's date to her cousin's wedding. At Thanksgiving dinner, Rex tells his family that he is gay. In the final frame of the film, a picture is shown of Lance and Mary getting married, accompanied by Ian. Lance is shown sporting a beard exactly like Ezekiel's.
During the credits, a short scene shows Ezekiel and Fall Out Boy arguing over the fact that the Amish fixed Fall Out Boy's tour bus for just "a five song set" in form for compensation, referring to a running gag throughout the movie.
