My Macbook Air Got Sat on and Lived!

I thought that I was in a Nightmare when I realized that my brother (who weighs 230lbs) was sitting on my laptop this weekend. To his defense he was drunk and he didn't see it so I wasn't mad. I got up and asked him "where did you put my laptop" and he said "what laptop". Right then I knew that my new 2012 13in. Macbook Air was a goner but to my surprise there wasn't any damage whatsoever. I was in total shock to see something so thin be so damn strong.

I sure am glad that I started used Macbooks recently because I doubt that one of my old Windows Laptops would have taken that.

Has anybody else had a similar experience?
