He sits at the counter and notices an old cowboy with his arms folded staring blankly at a full bowl of chili. After fifteen minutes of just sitting there staring at it, the young cowboy bravely asks the old cowpoke, 'If you ain't gonna eat that, mind if I do?'
The older cowboy slowly turns his head toward the young wrangler and, in his best cowboy manner, says, 'Nah, you go ahead.'
Eagerly, the young cowboy reaches over, slides the bowl over to his place, and starts spooning it in with delight.
He gets nearly down to the bottom and notices a dead mouse in the chili. The sight was shocking, and he immediately barfs up the chili back into the bowl.
The old cowboy quietly says, 'Yep, that's as far as I got, too.'
