Jack Vale is a YouTube prankster and entrepreneur, known for his invention, The Pooter which when squeezed makes a very realistic farting noise. According to Wikipedia "as of February 10, 2017, his videos have around 315 million views and his channel has more than 1.3 million subscribers." He has appeared on The Jimmy Kimmel Show as well as other TV shows.
Either Jack Vale is using The Pooter or his farts don't smell even though they sound like he's shit himself.
