I dump the contents from the canister onto a plate. What I pour is what I eat. If it's me and my girlfriend, then I'll pour the entire canister onto the plate. Sometimes we munch on two Pringles canisters at one sitting.
Sometimes one, usually more. It was Proctor and Gamble that invented Pringles, same people that own Tide, Pampers, Tampex, and bunch of other non-food products, makes you think...
I’ve never tried the Duck Bill technique but I still use about 5 chips when doing The Saddle. I might be able to eat just one chip, and one chip only if I were to put it in Reverse Cowgirl.
