Not me but a good buddy a few years ago. IHOP at 3 am Saturday night after a heavy night of drinking. Place is packed, we finish eating and are standing at the cash register while other friend is paying when buddy #1 says he's got a rip one. I say "shit in the microphone". He grabs the mic they use to call your name when there is a waiting list, squats in the perfect stance, and lets rip with an obnoxiously loud fart that is greatly amplified by the microphone and broadcast inside and out. The whole place that is full of loud drunks falls deathly silent. The chic working the register is staring in disbelief and manages to utter " I aint believing you farted in that microphone". I laughed so fucking hard I ended up in the parking lot tossing up the IHOP. I got home an hour or two later and was still laughing so hard when I got in bed I woke the wife up and had to tell her what happened in between laughs. I'm laughing my ass off right now just thinking about it.
