On a more serious note, this is what I have read about selecting a puppy. I myself have never picked out a puppy, so I can't personally vouch for this technique.

You don't necessarily want the puppy who runs up to you, because is more likely to mean s/he is the most adventurous and outgoing, rather than because s/he senses a bond with you. You probably don't want the puppy hiding in the corner, because s/he is likely to be shy.

To pick your pup, try gently rolling a puppy on its back. You want a puppy who maybe struggles a little bit, but sees it as a game. You don't want one that is overly submissive, or gets angry, or gets scared. Since dogs are not comfortable on their backs with strangers, this can indicate if your puppy will be playful and easygoing.
