Oh So Satisfying
I once channeled my inner 12-year-old and set a coworker’s (good friend) Windows start-up sound to a sound file of the juiciest flatulence I could find then cranked his speaker up before he got to work. The results were oh-so-satisfying. Once he got in, the dead silence in the office was abruptly broken with a giant PFFFFFFFTTTT, which was quickly followed by fellow officemates yelling at him for being nasty. I was crying from laughing so hard.
