It's amazing what fans can do. A hardcore My Little Pony fan decided to get together with a bunch of fans and sang this HILARIOUS song about CONVENTIONS. As reported from io9

"Griffin Lewis and Jenny Nicholson wrote this song for last weekend's Canterlot Gardens. It's an amazingly well executed piece based on the Stephen Sondheim-inspired "At the Gala" musical sequence from the episode "Best Night Ever." Nicholson herself does the voices of all six central ponies, with other folks chipping in as the chorus (which takes everyone down a peg with a bit of gentle mocking). And each pony's convention expectations perfectly fit her personality. Now if only there was a press person pony who could sing about cosplay photo safaris and the joys of sleep deprivation."

I'm not a Pony fan but this song just takes the cake and describes EVERYTHING about the con going experience
