I read something recently that claimed that Googol (the mathmatical term) was in fact a corruption of Google in the first place, though the evidence is thin, it's vaguely plausible:

The terms googol and googolplex were first published in 1940.
The word "Googol" was coined in the 1920s. There's speculation that the child who came up with it was inspired by a Comic book character called "Barney Google" who was famous at that time.
To be honest, that's just wild (and a bit arrogant) speculation on the part of the author. I knew about the comic book, so I expected at least an ounce of evidence, not just the author convincing himself...
