I cant believe no one posted this earlier. Did anyone do you anything to celebrate? Express everything in terms of pi? Tell time in radians? Eat things that have "pi" in them (pina colada, pine nuts, etc... not just pie)? Make a square pie and then say "pie are squared?"(my favorite). All I had was a physics test and a crappy math lesson. My teacher gave us 7 ridiculously hard integrals (we dont know how to do them yet) and asked us to solve them. It turns out that all of the answers were like..pi/2, root pi, etc. Lame.
