WILLOWBROOK, Ill. (WBBM) — The date Monday makes it a winner for those in the pie-making-business.

As WBBM Newsradio 780’s Michele Fiore reports, this is 3/14, or Pi Day. Or thanks to those with a penchant for homophones, Pie Day.

In Willowbrook at Bakers Square, they have been hinting subtly about the day for weeks. General Manager Terry Loggins laughs when she admits she doesn’t know all the digits beyond 3.14.

“My boss probably does, but I don’t,” Loggins said.

Actually, nobody does. Pi is an irrational number, so the numbers after the decimal point never end or repeat. (If you’re curious, click here to see pi expanded to 1,000 digits.)

In any event, the Willowbrook Bakers Square has a special offer Monday.

“The first student that comes in to buy a pie, we are going to sponsor the students in their class to have free pie for Pi Day.”

It’s not just a Bakers Square thing – many bakeries are offering Pie Day specials.
