I would have blown milk out of my nose when I saw this.
Had I actually been drinking at the time.
The trainer holding the tray of cupcakes is trying to teach Stains the dog to "leave it" (only she uses the command "away" only that seems awkward to me so I revert back to the command that I'm used to). His face is awesome.
Kind of reminds me of this picture of Gabe that I took when he was three-months old that also involves a stare down with a cupcake.
