Sponge Day 

The best thing since Porch Day. On Bungie's off topic forum, The Flood, many parody threads were made referencing various characters' views/memoirs from the Spongebob universe.

Example of Sponge Day:
Topic:What the hell?
Post:This sponge and his snail just moved into me! Help!

(From the view of Spongebob's house, a pineapple)

National Give Den a Sponge Bath Day 

April 19th, give your Den a nice deep cleansing sponge bath. (Using a sponge is optional, you can use whatever you have on you that is handy, ie tongue etc).

Shocked by how filthy and dirty Den was, I decided to give him a sponge bath on National Give Den a Sponge Bath Day. A perfect day for a nice deep spring cleansing, get deep in all the cracks and crevices.
