Everyone knows that Citizens Bank Park is now the place to be in the summer in Philly.

It’s a destination point. Party Central. And, by the way, they also play baseball games there.

Last night it became official. Citizens Bank Park received the ultimate emblem of a place that has arrived.

Jack Nicholson was in the house. Now that’s cool. The star was right there in his field box. You almost expected a Lakers game to break out.

Nicholson is in town to film a movie.

Only one problem. Nicholson was wearing a white Yankees hat.

What’s up with that?

Yo, Jack. This is Philly. We don’t do Yankees.

Last night as you might expect, the Phanatic got into the act, doing a takeoff on Nicholson’s Riddler character from the “Batman” movies. And Nicholson went along with the joke. Of course, the Phanatic did not dump a box of popcorn on Nicholson, as he sometimes does with fans wearing the attire of other teams.

That would not be cool. Neither is that Yankees’ cap, Jack.
