Send a Fart in a Jar

You can now send your smelly farts in a jar. Seems revenge is doing good business as of late.  You can anonymously send a fart in a jar to the recipient of your choice.  For ten bucks (3.50 shipping) you can let it rip from three different fart fragrances: 8-hour Trucker Fart, Hungover Frat Boy and Competitive Eater.
Now imagine the look on their face when they realize they just inhaled an invisible turd. And once they've breathed in the surprise stench, you're done. It's the perfect way to tell someone how you truly feel without ever having to say a word.
