Surely you saw that in the news a year or two ago.
EDIT: Okay, since this really can't be construed as being political, the following have been chastised in the New York press for eating pizza with a knife and fork: DeBlasio, Trump, Kasich.

In any case, I'll typically order a basic pizza from one of the usual suspects and do the toppings myself.
