It doesn't get much more craptastic than this — Sammy Davis Jr. sings the theme to "My Mother The Car," one of the worst sitcoms in television history. What the hell was he thinking!?
UPDATE 5/30/2010: YouTube has blocked my clip, so here's another one… and this one is even better. You can actually see Sammy performing the song with dancers on his TV show!
But wait, there's more! Here's Sammy singing the theme to "The Jeffersons"
And, in case you missed'em before, here's Sammy singing the themes to KOJAK, HAWAII FIVE-O, MARY HARTMAN, CHICO AND THE MAN and MARY TYLER MOORE SHOW
