Garfield is a comic strip created by Jim Davis. Published since June 19, 1978, it chronicles the life of the title character, the cat Garfield (named after Davis' grandfather); his owner, Jon Arbuckle; and Arbuckle's dog, Odie. As of 2007, it was syndicated in roughly 2,580 newspapers and journals, and held the Guinness World Record for being the world's most widely syndicated comic strip.
Lyman was a friend of Jon's, who lived with him for a while and was the original owner of Odie. Lyman was one of the main characters in the comic strip along with Garfield, Jon, and Odie. The comic strip usually had four main characters, but that number was reduced to three when Lyman was cut out of the strip by Jim Davis.
Beach Blanket Bonzo is an episode from the second season of Garfield and Friends. Jon tries to impress a girl at the beach, and Garfield doesn't understand how anyone could go crazy over a pretty face until he falls in love with a female cat.
