If You Want Something Done Right, Do it Yourself

A Stock Phrase. Characters who use this phrase are usually the ones who decide to do something their subordinates failed to do on their behalf. Never send an amateur to do a job you need an expert for, namely, the guy in charge.

The hero, anti-hero, or sidekick might discover her teammate in the Five-Man Band dropped the holy gem needed to defeat the god villain, was killed off, or simply missed the plane. The villain, anti-villain, or last remaining sane mook might notice that the other mooks didn't kill the hero. Either way, this person gathers the team's weapons, spells, and doomsday devices, and mutters "If you want something done right, do it yourself."

Whatever the case, someone - possibly a Non-Action Guy, Non-Action Big Bad, Retired Badass, or someone who otherwise avoids getting involved is sick of having to relay the important tasks to incompetent underlings who keep messing up. Punishing or berating them doesn't help, and the replacements are just as bad. Whatever his reasons are for avoiding taking action, he can't stand on the sidelines any longer. Time for Orcus to get off his throne.

If Authority Equals Asskicking, then this is a character's chance to prove it or risk being shown to be a Paper Tiger. This may lead to a potent and epic confrontation, or it may lead to whoever it is remembering just why he doesn't do it more often. One way or another, however, it's going to end differently.

 * Garfield and Friends:

 * In another episode, local mailman Herman Post was fired and his former boss, not able to find a mailman willing to take over the turf out of fear of Garfield, decided to deliver the mail himself. After enduring Garfield, he begged Herman to take the job back.

 * In the Codename: Kids Next Door episode "Operation: T.R.A.I.N.I.N.G.", Father invokes this Trope after yelling at his moronic henchman who didn't know the vault at the Arctic Base was locked, and starts burning it open on his own.
