July 4th, 2005 - My friends and I, after a few drinks on the beach, stopped at a Denny's for a restroom break.
So, I'm in the Denny's men's room, taking a leak, right next to a stall. As I start to relieve myself, I hear a wind instrument playing in the stall. The pitch range of the instrument was quite impressive, and it wasn't in a hurry to stop playing. At this point, it's kind of like a life/death situation where time slows down and each second feels like a minute, you know ?
So, I'm counting - 3 seconds, 5 seconds, 10 seconds, ... and on, while the symphony is in full flow. And while I'm counting, my whole body is shaking so violently with muffled laughter that, after a few seconds, I'm no longer able to aim at the latrine. It's all over the place

I hope Denny's will forgive me for that
Of course, I'll never know the exact duration, but I'm willing to bet the symphony lasted a good 20-30 seconds of flute powered by Denny's Di-Sulfide.
I can't remember what ended first - me relieving myself, or the symphony

Anyway, by the time I was done, my face was a scarlet red from all the fresh blood pumped into it.
So, then, I stumble out into the dining area, still violently shaking from the muffled laughter, but trying my best not to appear like I'm deranged. I finally emerge outside the Denny's, where my friends were waiting for me.
They could see that something worthy of knowing had transpired. When asked, I tried (and tried and tried) to stop laughing so I could tell them what. It took me about 5 minutes before I could finally calm down enough to tell them what I had just experienced.
My friend and I call the unknown musician "Denny the Destroyer (of bowls)"
