This user's username is derived from a Calvin and Hobbes strip in which an alien appears to Calvin. The alien promptly changes himself to look like Calvin. Calvin then introduces himself, saying "Hi, my name is Calvin. Have a good day at school" and hands the alien his lunchbox and books. The alien then talks to various characters of the comic strip, repeating the phrase Calvin told him, but pronouncing it differently (e.g. "Ha ma nam es Kahlfin. Haf agood day askool."). In the final frame, the alien in Calvin form is drawn with Calvin's Mom and Dad as well as the principal of Calvin's school, saying "It troo. Dat darn Kahlfin stole ma spaceship." The name Kahlfin is taken from the alien's pronunciation of Calvin.
