Tail-chasing dog doesn't know what he's got 'til it's gone8/25/2012
"Look at this idiot I have to live with. He's just too stupid to live. Hey, bozo – it's not another dog. It's your tail. It's attached to you. Even if you do catch it, what are you going to do with it? Stop, already! You're making me dizzy. Gad, the people in this house need to sign him up for a course in remedial dog. OK, brainiac, you keep chasing. I'll just sneak in here and take this chew toy since you don't seem to have any use for it. Oh, what happened? Did you lose your bone? What ever could have happened to it? Hey, look behind you – maybe your tail took it."
How did one dog get so smart and another get so dumb?
