A math joke

I think it doesn't work well as a joke because it uses two Greek letters in a row but expects the reader to interpret them in contradictory ways: the first by the mathematical concept it represents (but not its name), and the second by its name (but not its mathematical concept). I got the gist of the joke, but not its specifics, because I kept reading the sequence as "i 8 sigma pi."

Sounds like a frat party gone wrong.

You beat me to it (deliberately or accidentally)

Quite deliberate.

The OP might mean 'i 8 alphabet pi'. That would be more delicious. How about this?
√(-1) 2^3 ∑^a
That makes a little more math sense to me.
