Some holidays/national days lend themselves to food specials and giveaways more than others.

Today is March 14, or 3-14 -- Pi Day. Pi is the equivalent of 3.14159265359, which is a mathematical constant that is the ratio of a circle's circumference to its diameter. It is represented by the Greek letter π, which is pronounced pi.

So, a pie giveaway. Well, then, that only makes sense.

For Monday, St. Patrick's Day, a couple of national chains are doing food specials. One works; the other, not so much.

Sonic is doing half-price cheeseburgers all day in celebration of the day. There are Sonics located in Comstock Park, Wyoming and Portage.

Now, to be honest, what cheeseburgers have to do with Ireland and St Patrick's is beyond me, but it works.

Then there is the bagel chain Einstein Bros., which has a location on Grand Valley State University's Allendale campus.

Einstein Bros. is doing green bagels for Monday.

Green beer, OK.

Green food, sure.

Green bagels? I think I will pass. I mean I know it's just food coloring in the dye, but still.

Happy St Paddy's Day!
