Having gas in public can be an embarrassing ordeal. Or it can be hilarious.
This dude decides to hide a "fart machine" in his pants as he goes to an airport and boards a flight. The noise maker is synced to an app on his phone and plays a series of pre-recorded sounds when triggered by a button in the app.
Another dude nearby records people's reactions as fart dude ventures around the airport and as he boards a flight. Thankfully for the "victims" in the prank, the farts were not real.
