One Time Gags

This is a category for the various one time gags executed throughout the How I Met Your Mother series.

One Time Gags refer to any gags in the series that are only mentioned and only occur in one episode. Most of these gags are of a humorous nature, however they do not have to be. If the gag is mentioned in multiple episode, or takes place over multiple episodes, it becomes a Recurring Element.

For example, as the Mermaid Theory is only mentioned in one episode (The Mermaid Theory), it is considered a one time gag.

As Barney Stinson's love of laser tag is mentioned and shown throughout the series, in multiple episodes, it is considered a recurring element.

Although Ted's fight with the goat only occurs in one episode, because reference to this fight is made in several earlier episodes, it is considered a recurring element.
