I have the power

One of the key statements during wimpy-ass Adam's most inopportune (for Skeletor anyway) and last-minute transmogrification into HeMan, Master of the Universe.

In the remaining five minutes of the episode he then promptly recovers from an impossible situation by pulling a Jerry Springer on the unsuspecting Skeletor and/or his minions yet leaving enough time to go home for scones and tea and an important moral lesson (by Orco nonetheless) that somehow sidesteps and makes wrathfully righteous the issue of the mass genocide of Skeletor's enslaved race of minions

A phrase uttered by many a woefully naive child before they attempt to tackle a semitrailer with their bare hands.

Also: "By the power of Greyskull!" Adam yells this whenever he takes his bad-ass sword, lifts it above his head and, without a single bench press or sit-up, suddenly has some big, buff muscles and becomes He-Man, Master of the Universe. He typically does this a few minutes before the end of the show. Then he goes and kicks Skeletor's ass. But first he points the sword at his green whimpy pussycat to turn it into a big lion-like thing ready to tear Skeletor in half.
