I was sitting outside the other day, and I saw the fattest pigeon.

He was fighting with a couple other pigeons over a crumb on the ground. The fat one was losing. In the end, he didn't get the crumb. 

Watching the scene made me think about taking too much. Doing anything impulsively and selfishly (in the pigeon's case, eating to the point of obesity) will eventually fuck you over.
