We've all been there: a night of heavy drinking ensues, and the next morning, you struggle to remember the events of the night before. It's the simple plot behind the blockbuster film "The Hangover," but it is a plot that also shows up in plenty of TV shows. From comedies to serious medical dramas, these shows feature great episodes where characters have to retrace their steps to relive what happened the night before.
The episode "Last Night Gus" was an homage to "The Hangover," and featured Gus, Shawn, Lassie, and Woody the Coroner trying to piece together the events of the night before. The episode opens with the four guys waking up in Shawn's office, with Lassie sporting a serious shiner on his eye and missing several bullets from his gun. More troubling, Gus finds that his car has been trashed, and a murder occurred the night before that the guys may have been involved in. It's one of the best episodes in the whole run of the series.
There have been a couple of "House" episodes where the eponymous doctor has had to try and figure out what happened to him the night before. In the fifth season finale, House wakes up after sleeping with Cuddy the night before, and has to try and recall what happened the previous night. In the two parter "House's Head"/"Wilson's Heart," House needs to recall the events that brought him to a strip club, where he wakes up with an injury to his head.
In a very funny episode, teetotaler Sheldon is convinced to have a few drinks to relax before giving a speech. The next morning, he has to ask his friends what happened, because he was too drunk to remember. His first question is regarding the location of his pants. Leonard quips, "Check YouTube." Poor Sheldon really could not hold his liquor.
In a very clever twist on the classic "What happened last night?" formula, the "Warehouse 13" episode "Love Sick" had Pete and Myka engineer a scenario where they would think they had slept together the night before. In fact, they didn't: They got into bed together because the idea of sleeping together was so ludicrous, it would ensure that they would be compelled to retrace their steps from the night before (and find their missing friend).
In one infamous episode, Ted had a very wild night. The next day, he has to remember how he sprained his ankle, hooked up with a random woman, burned his coat, and got a number written down on his arm. Nearly all of these mysteries get answered, save one: Where on earth did that pineapple in his bedroom come from? The world may never know.
