Google

 Barb's friend calls me "Google" in a nice way because she says I know everything. Tonight, Barb was talking about the mystery novel she was reading that was set in a small town in Quebec about a mysterious "big gun." I started talking about Gerald Bull. She looked at me, shocked. How did you know about Gerald Bull? He is mentioned in my book. I said he was a defence scientist in Valcartier who invented a giant gun to shoot satellites into space. Barb couldn't believe he was a real guy, and I knew about him.
