Why is pie one of the most used thing when people are asked to be random?

Actually, it's quite simple.
It has nothing to do with "pie", but instead, it has to do with "Pi".
As "pi" is very look alike, phonetically, with "pie" and it's a very random number (the numbers don't go سے طرف کی a certain order یا rule), people associated "pie" with random.

Because people are weird. Honestly, Idont think pie is that good. Please dont be mad at me for saying that pie lovers

This is exactly why I کہا that pie doesn't seem that random anymore. It's expected. I honestly don't know. I like pie, but why? Hey, that rhymes :')

But I don't know. I guess it's just one of those things that catches on. :P

pie is awesome. i can throw a pie at ur face, pie myself, یا throw it at a computer when i get frustrated with it, pie wins

Pie.
