Of course, the way I learned it, e^(iπ)+1=0, which is 180° from the way this cartoon has it... perhaps that's the point of "now you're just fucking with me"?

One of They Might Be Giants' early podcasts started with a song with every verse starting "When I was... [insert number or name]" - and the second verse was, "When i was the square root of a negative number..." :-)

Cute.

P.S. apparently I can't use the <sup> tag in this comment box, which is rather a nuisance for writing exponents...
