G-man

G-Man is a character from the X-Box/PC video game series Half Life. On YTMND, he achieved fad status when Ixian created "Gman's having a wonderful time", a YTMND with an animated GIF of G-Man spinning around in a chair in his office, accompanied by the song "Livin' in the Sunlight, Lovin' in the Moonlight" by Tiny Tim. Since then, many G-Man YTMNDs have been created. Two notable ones are "Gman is NOT having a wonderful time", where G-Man gets off of his chair and throws it into a window, and proceeds to destroy more stuff and eventually blows up the whole chair with a bomb. Another notable one is "Gman was Suicidal (Before He Had a Wonderful Time)" where he attempts to kill himself multiple times but finds the chair (and happiness).
