I know the math term, we used to have a "GoogalPlex" movie theatre here some decades ago- or was that a Simpsons episode, lol? It all blurs together. As I recall, a Googal is something like 10 to the hundredth power.
Barney Google predates the cartoon, which I remember from my youth. My grandmother used to sing the Barney Google song which dates to the 1920's, I believe. I found a recording on YouTube.
