Pi Chart

A bar chart whose adjacent vertical bars have heights proportionately based on the digits of the decimal number π—from a distance, the statistical diagram looks like a city skyline.

On a graph paper, what is the most number of bars you can draw for a pi chart?

Pi in the Sky

When the passengers on a plane up in the sky are separately seated based on the the digits of the decimal number π—there are three empty seats between the first and second passenger, one empty seat between the second and third passenger, four empty seats between the third and fourth passenger, and so on.

On a Boeing 777, how many passengers could take part in the “pi in the sky” experience?

pi-gu

Variation of Mandarin Chinese, roughly translating as "rectum", "bunghole" or "asshole" (but not a person who's an asshole.)

"You think you're better than other people!"
"Only the ones I'm better than. And now I'm thinkin' that's the very thing you're placing value on today."
"I place value on the fact that the stick up your pi-gu is about as big as the one Harrow's got."

Pi Persecution

When the number π is being spied 24/7/365 online and trolled by envious or jealous numerical constants, who couldn’t stand her global appeal or fame, as thousands of mathematicians and math educators worldwide maniacally devote an obscene number of hours every year trying to discover hidden properties about her.

Constants like e and 𝛷, conspiring with √2 and i, have been repeatedly accused of pi persecution, because they’ve allegedly or unprovenly ganged up to serially and spitefully downvote any old and new Urban Dictionary entries on π every day.
