There's a first time for everything.
Actor, 72, shared a photo with his Twitter followers on Wednesday capturing what he called his "first ever pizza 'slice.'"
"Please note the authentic NY fold," Stewart wrote alongside the picture.
In the photo, the actor sports a (Montreal Canadiens) Habs hat and drinks from a small beverage cup.
He followed up that post by tweeting: "To clarify: 1) I've never had a 'slice' 2) I've been a Habs fan all of 4 weeks 3) I'm also a fan of Bloomberg's soda legislation."
