Swap Meat

Swap Meat is the 12th episode of Season 5. 

Synopsis
A teenage nerd conjures up a spell to swap bodies with Sam. After the switch, the boy investigates a case with an unwitting Dean and enjoys the perks of being good-looking and older. Meanwhile, Sam is stuck in the kid's body and deals with intrusive parents and high school.

Plot
When nerdy teenager Gary and his two friends Trevor and Nora are playing with black magic, they come in contact with demons and are informed of a bounty out on Dean Winchester's head. When Dean and Sam arrive in town to exorcise a poltergeist, Maggie Briggs, haunting the home of their old babysitter and her family, Gary casts a spell which has him and Sam swapping bodies intending to hand Dean over to the demons.

Gary gets rid of all Dean's cell phones so Sam can't contact him and poses as him to accompany Dean on the case, where thanks to Maggie Briggs, he misses an opportunity to kill him. Later he celebrates the ghosts' vanquish, enjoying getting drunk with Dean, and later getting picked up by and going home with a woman from the bar. When he comes back to the motel, set on killing Dean, Dean has worked out he is not Sam and confronts him.

As Sam struggles to work out what has happened, and deal with Gary's overbearing parents, he discovers Gary's spell book and his involvement in witchcraft. Trevor and Nora drug and capture Sam at school, knowing that it's him in Gary's body, and against his warning, Trevor summons a demon to hand over the brothers and claim their reward. The demon possesses Nora, kills Trevor and then takes off to claim Dean.

Dean is in the middle of interrogating Gary, when the demon arrives and knocks him out. The demon tells Gary he will get his reward but he must meet with Lucifer first and say 'yes' to his question, intending to hand over Sam's body to be used as Lucifer's Vessel. Gary, regretting everything tries to exorcise the demon but it attacks him. Eventually, Gary and Dean team up and exorcise the demon together. Gary then reverses the spell allowing him and Sam to regain their former bodies. Sam leaves him with a stern warning to stop using magic and that his life really isn't that bad.
