Leslie and Ben
Parks and Recreation Season 5 Episode 14 (02/21/13)
When Leslie and Ben decide to get married at the gala, they assign the entire gang to specific tasks. April and Andy get the marriage license signed, Chris and Ben look for rings, Donna and Jerry run the gala, and Leslie and Ann try and figure out Leslie's dress.
Chris and Ben can't find nice rings, so Ron decides to make the rings from the light in Ann's house at the last minute. With everything thrown together, the group heads to the gala and Ron walks Leslie down the aisle. Unfortunately, Councilman Jamm decides to interrupt the ceremony with taunting and stink bombs. When he says some mean things about Leslie, Ron punches him and the face and they both end up in jail.
The wedding is put on hold because the gala has ended. Once they bail Ron out of jail, Ann suggests a drink at the office to take Leslie's mind off of the night's events, but when Leslie arrives, all of Leslie's friends and Ben have set up the office for a wedding. Ron walks her down the aisle and Tom marries Ben and Leslie.
