About a week ago, I saw someone respond to a question of Facebook with the reply, "I'm as happy as a parking lot bird with a french fry." I thought that was a pretty clever reply. Who hasn't seen a bird in a parking lot go into culinary bliss after finding a french fry on the pavement?

Well, the crow in this video is, I'm sure, as happy as a bird with a french fry. He/she also happens to be one pretty darn smart as well as quite tenacious. The crow knows there's something to eat in the box and you can actually see the bird trying to reason out how to get to the goodies inside.

Watch as this crow finally masters the secret of opening a pizza box and getting his partial slice of pizza crust as a reward.
