|Season 3, Episode 39|
|Premiere date:||September 3, 2012|
Mordecai and Margaret finally kiss, but Mordecai is left disappointed after it was cut short by his bad breath, and wants to go back in time to redo it.
It starts with Mordecai, Rigby, Margaret and Eileen leaving the movies, and driving to the park. When they get there, Mordecai says he forgot his wallet in Margaret's car, so he goes back to find it. A couple seconds later, Margaret shows up, and tries to help him find his wallet. When they get close, they kiss, but Margaret pushes Mordecai away because his breath smelled bad from a chili dog he had earlier.
After being embarrassed, Mordecai grabs Rigby and runs inside the house. He explains that him and Margaret were in the moment, and they kissed - which Rigby didn't believe - but Mordecai says how his breath smelled bad, and how he would be embarrassed forever. Rigby then pulls out a 'time machine', even though Mordecai doesn't believe it works. When they mess with its button, it sends them 15 minutes in the past.
In the past, they see a past Mordecai running to the car, then they press the time machine's button - sending them further into the past. They try to go back many times to keep Mordecai from eating smelly foods, to prevent him from having a bad kiss. They eventually end up going back to that morning when Mordecai was in the bathroom. They try to force the past version of Mordecai to use mouth wash, but when he doesn't believe the present Mordecai and Rigby's story, he takes the time machine from them and goes into the future to kiss Margaret.
Thankfully, Rigby has another time machine, which he says that he got $3 off for a double order, and they go after the past Mordecai. While travelling in time, there are a lot of appearances from previous episodes. When in the process of traveling through time, Mordecai tricks the past Mordecai so that he can keep him from kissing Margaret.
They finally reach the past Mordecai, and Rigby uses one of the time machines to take him to the future. Then present Mordecai and Rigby break the time machines, causing everything that just happened (between his first time travel to the machine's destruction) to have never happened, and time is set to where Mordecai is in Margaret's car. However, Mordecai doesn't want to have a bad kiss and realizing his breath is still bad, he abruptly finds his wallet, stopping Margaret in mid kiss. Then, they get out of the car to join Rigby and Eileen (to have shakes). The episode ends with them entering the house, leaving Mordecai without a kiss from Margaret.
