Piggy Bank Day is an event that appeared in "Fa-La-La-La-Ed." It is apparently held in July every year. On Piggy Bank Day, everyone smashes open their piggy banks and spends the money. On the day it happened, there was a party at Jimmy's house, complete with pig-themed food and games. All of the kids attended, and most of them wore pig noses to commemorate the day. Eddy attempted to make some money off of the holiday with the Piggy Bank Belly Pumper, but failed to do so after Ed exposed the inner workings of the scam. Later, the event was abandoned in favor of Ed's Christmas cheer.
- The event is confirmed to happen in July, as repeated assertions of the month by Eddy (and to a lesser extent Kevin) were made.
- Before the events of "Fa-La-La-La-Ed," Eddy had never heard of the holiday. This is probably largely due to the fact that he never had enough money in his piggy bank to have a reason to smash it and to the fact that the Eds rarely, if ever, get invited to any parties (Plank's Groovy Arbor Day Party being one of the few exceptions).
