MacGyver

The Series
MacGyver was an action/adventure series that ran from the mid 80s to early 90s, starring Richard Dean Anderson in the lead role of MacGyver, a secret agent who was excellent with whipping up inventions from things that are actually fairly useless.

It is generally covered by the Sub-Department of Rare Fandoms in those instances where the series and characters catch a Sue's eyes.

As a Verb
As a verb, MacGyver means to create or do something by using fairly common materials in a creative way.

Agents are generally discouraged from MacGyvering and leaving the creation of inventions to the Department of Sufficiently Advanced Technology, as they have a tendancy of doing this to facilitate their own bad ideas. That, and things tend to explode when most Agents try this.
