Marc Cosentino, co-owner of Goodfella's Pizzeria, said he set aside the fork that sparked "Pizzagate" when the mayor was videoed using the utensil to eat his pizza instead of using the traditional bare-handed approach, DNAinfo New York reported Friday.
Cosentino, a retired police sergeant, said he obtained an evidence bag from a police friend and used it to display the fork behind the restaurant's bar.
"I just did it because I thought it was funny," Cosentino said. "Then all of a sudden it got all this interest, so I thought let's do something, let's do something for charity."
Cosentino said the fork will be auctioned for charity.
The "Pizzagate" scandal started online following De Blasio's use of a fork and knife to eat his pizza at Goodfella's, and "The Daily Show" host Jon Stewart dedicated five minutes of Monday night's show to mocking the mayor.
"I understand there's a learning curve to being mayor, but here's lesson No. 1: Learn how to eat your city's signature dish," Stewart joked.
The mayor blamed his Italian ancestry for his pizza-eating habits.
"In my ancestral homeland it is more typical to eat with a fork and a knife," de Blasio said. "And so I have been in Italy a lot, and I picked up the habit for certain types of pizza."
