No, that's what people generally think.
it was a character from a comic I read as a kid. Krazy it was called, big high point of the week when it appeared on the kitchen table, besmirched being within touching distance of my sisters 'Jackie'.
Anyho, there was a character in there that liked nothing more than being filthy as much as possible, Pongo Snodgrass, so the Landy became Pongo.
Slightly personal confession thinking about it but hey......
