Great post on Gilbert Arenas's blog; here's an excerpt:

We’re humans. We live on land.  Sharks live in water.

So if you’re swimming in the water and a shark bites you, that’s called trespassing. That is not a shark attack.

A shark attack is if you’re chilling at home, sitting on your couch, and a shark comes in and bites you; now that’s a shark attack. Now, if you’re chilling in the water, that is called invasion of space.


 
Hilarious stuff.
