I would post side-by-side pictures for greater effect, but that requires some GIMPing. Still, if you were reminded of P. Diddy during the close-up milk drinking shot in Napoleon Dynamite, it was for good reason.
Here's P. Diddy's mouth and here's Napoleon Dynamite's mouth. Notice, in particular, the philtrum of both.
Now imagine equipping Napoleon with bling, a hat and dark glasses, and cutting his fro. Or, to go the other way, imagine letting P. Diddy grow his fro out and giving him some reading glasses. It's a great Photoshop opportunity.
