Comedy Central’s Jon Stewart mocked Donald Trump Wednesday for eating pizza with a fork during his dinner with Sarah Palin.

“Based on how you eat pizza, Donald, I want to see your long form birth certificate. I don’t think you were really born in New York,” Stewart joked.

Trump seemed to be responding directly to Stewart when he defended his eating style in a video posted to YouTube.

“A lot of people are asking about why am I using plastic forks and knives that the pizza parlor gave,” Trump noted. “Well, I don’t walk around with forks and knives and frankly it was very confortable.”

“Plus, this way you can take the top of the pizza off and you’re not just eating the crust,” he added. “I like not to eat the crust so that we keep the weight down at least as good as possible.”
