Sue Gazoomy, Sue Good God
I can see why Google would make the attempt but it really was far fetched. It's as daft as trying to sue any website that starts with G and contains a couple of O's. Gazoomy.com does the same thing for example, and I'm sure after a night on the tiles and a raging hangover your blurry vision could be used as an excuse for typing in Gazoomy instead of Google!?
The irony is that both Groovle and Gazoomy accrue revenue for Google, so you could say that Google are suing their own right foot.
It's a strange world we live in.
