The clip comes from a short video posted in 2015 by internet personality WelvenDaGreat, real name Welven Harris, who tells the Deez Nuts joke to a friend on the phone. The video spread quickly on Vine and Instagram, turning his laugh and the phrase got em into a catchphrase. Deez Nuts itself is an older slang joke, but this version gave it a recognisable voice and timing. It remains a staple prank sound because the punchline is instantly understood and works over almost any setup.
