Supernatural (Anime)/Recap/S04 E08 Wishful Thinking

Season 4, Episode 8:

Wishful Thinking
Sam and Dean investigate a small town where the wishing well really works. A teddy bear comes to life, a boy who is always bullied gets super strength, someone wins the lottery, and the town geek gets a hot girlfriend. The brothers realize that while everyone is happy now, the end result will be disastrous. The boys find the cause of the wishes are a magic coin that causes a fountain to become a wishing well and that the only way to reverse the wishes is for the person who put the coin there to remove it.
