And here I thought the Escapist was full of intelligent people... did somebody really just quote Bill O'Reilly in a positive light?
OT: Easy answer: Depends on the sort of restaurant I'm at. If it's a take-away, with my hands*. If it's a swanky restaurant, with a knife and fork. Always pointy end of slice first.
*If the pizza is in 6 slices or if I need to slice it myself, I will slice it into 6 and take alternate pieces so after 3 slices I can have the radioactive symbol made up of pizza slices. In my head I am an eight year-old.
