Mandela Effect - Dr. Evil Puts His Pinky Where?

Well, if you watch all of the movies, he puts it in various locations -- sometimes between his lips, sometimes just under his nose, sometime to the side of his chin just under his mouth...

So the answer to the OP's question is "several different places", so different people might have different answers depending on which scene they think of when they think of this -- although I think the intention is to put it between the lips, but Mike Meyers hand wandered a bit every now and then.
