Eureka - "I Do Over" (spoilers)
On Allison and Stark's wedding day, Sheriff Carter finds himself stuck in a time loop; causing him to experience the same lousy day over and over again. Meanwhile, Sheriff Carter's sister, Lexi, visits Eureka.
Sounds like Carter is experiencing another Bill Murray movie.
