Couples to say 'I do' at Center City pizza shop on Pi day

CENTER CITY (WPVI) -- March 14 is also known as Pi Day.

That's because the date 3-14 matches the first three numbers of the mathematical constant Pi.

"And Pizza" in Center City will once again celebrate by hosting two free weddings Thursday.

This is the fourth year the restaurant has done this at several of their franchises.
