The Asshole Next Door
 During the night (or when they're not home) take 10 packs of the old Alka-seltzer and drop it down his hose, then fill the open end up with Glue (a caulking gun works best). Then wait till he tries to water his lawn and watch the hose explode in his face.
 Break up the Alka-seltzer and sprinkle it all over his lawn.
 Feed it to his dog. (It makes them Fart Bad!!!)
 Put it in his Gas Tank of his car. The more you put in the better.In the Supermarket
 Hide one in a Tampon.
 Empty out a nose drop bottle. Then break the Seltzer up into dust size pieces, and put them in the bottle. Re-seal the bottle and put it back on the self.
 Put it in Tooth Paste.In School
 Drop one in the Fish Tank in Biology.
 Shove some down the drain holes in the Drinking fountain.
 Place one in a hamburger during lunch.
 Drop it in somebody's project in Chemistry. (You get some strange effects with this one!)At the park
 Feed alka-seltzer to a seagull and watch them explode.
 Give it to little children and tell them it's candy.
Well, that's all I can think of right now. Maybe if I get bored again I'll add some more to it. But Probably not. It's not worth it!
