Pi/Pie

     Is it just me or does anyone else think that there must be a correlation between the two?  You know, Pi - circle, and Pie - circle.  Or is this a common factoid that all humanity knows except me?  If so, be kind and don't scorn.  I didn't even know what a Pi was.  And isn't that just the freakiest thing you ever heard?  How does it do that?  3.14159 every time!  My mind is officially blown.

     So, who's gonna research this circle comparison thing for me?  I just don't have time - too much math homework.
