"Actually, my name, if you had bothered to ask, is Keith."
Geddit?! He's been through the desert on a horse with no name! You know, like in the song? Oh, suit yourselves.
Perhaps the joke is a bit obscure, or expects a bit of a leap of logic, either way this cartoon is a long-time occupant of the rejected pile. Click the link for more Not Yet Sold cartoons.
It made me laugh, anyway. I liked the idea of a horse called Keith. My kids have a similar sense of humour, I think. We recently got an adorably cute kitten and they decided that he is to be called Mike. Not Fluffy, or Mr Tibbles. Mike.
