It's Cal Worthington and his dog, Spot...
Owner of a chain of car dealerships and my personal childhood bogeyman. For those unfamiliar with him, Worthington is an ancient, leering old man whose dentured smile seems to be permantly etched in his leathery face. He is almost always seen wearing a white cowboy hat which covers something that is either a very bad toupee or an angry tribble with a home perm. Rather than bothering with mock sincerity, Cal ludicrously claims that he'll "stand on his head" if you can find a better deal while his beady little eyes twinkle greedily amidst his crow's feet. This is the sort of man mothers warn their daughters not to take candy from.
Cal's commercials typically consist of him riding, walking in with, or otherwise carrying some sort of exotic animal that he claims is his dog Cerberus-- I mean Spot. Cal then gives his standard spiel about standing on his head, and then a trio of unseen singers, as hellish as the erinyes sing his horrible, maddening jingle that will continue you to taunt listeners for hours. "Go See Cal, Go See Cal, Go see Cal!".
