Just saw The Sponge yesterday. When Elaine says something like "I'm going to search every drug store, general store, discount store in a 25 block radius," this is obviously a reference to the movie The Fugitive (when Tommy Lee Jones says "I want you to search every house, outhouse, hen house, treehouse, whore house in a 25 mile radius," or something). I'm just to lazy to go to google and see if this was mentioned already.
