In Penny's show, Kathy Smith Goes to Maths Camp, Kathy Smith talks about finding Horsham on Google Earth (she's a teensy bit of a nerd).

Anyway, so now everyone in my house is sitting around looking up stuff on Google Earth. We've found my old house in Boston, and the place down the road from there where I used to get cheesecake icecream (seriously), and the place where I used to chuck a frisbee with a guy called Jim who I once told a joke to about a war veteran and then turned out his dad was a war veteran and the joke wasn't very funny and that was a bummer because it's the only joke I've ever remembered. We've found Boston College (and the Boston College football field which is the size of some island nations in the Pacific) and the resevoir I used to walk around to get to college every morning. We've found my house in Melbourne. We've found the university and I remembered how I used to play hockey and wondered what's happened to that part of my brain (what does it do now?).

Anyway, now it's getting silly. We tried to Google Earth Paris Hilton's house.

So I've decided I'm going to read some more of my book, Surely You're Joking Mr Feynman, because in his spare time while he was studying at college, he worked out that if a trail of ants came into the cupboard of his room while he was studying, he could circumvent their trail to the cupboard and redirect it back outside, via a pile of sugar, merely by making individual chair lift things for each ant and redirecting them all for an hour, until all the other ants followed. It's got to do with the little trails of acid they leave around the place.

That is what he did in his spare time.

Actually, now that I think about it, he's exactly the kind of person who would spend hours on Google Earth. Possibly not looking up Paris Hilton's house.

In our defence, we were only looking it up because we thought she probably had a pool we could see from the air.

Because that's a good excuse.
