Fishsticks
I used to work in a team for a boss who had a separate office, but would come into our communal area when he wanted to fart. After he did this a few times I said that if he did it again I would take revenge. He did it again. So... I bought a pack of frozen fish fingers and while he was out of his office I opened his PC and placed the packet inside, unopened, and shut the PC again. The next day, Friday, the thawing fish fingers with the help of the fan inside the PC maintained a "just farted" smell in his office from 9-5. He had become immune to the smell but everyone who visited him that day emerged with an offended and quizzical look on their face.

The joke backfired a bit because I had to come in at the weekend and remove the packet which smelled VERY BAD indeed, especially since the air conditioning had been switched off, but apart from that the revenge was perfect. And he never farted in front of us again.
