You may or may not recall my post a while ago about a guy who works in my office who constantly whistles, and how I scared him shitless, and hadn't heard any whistling for quite some time. However, apparently I didn't make myself clear. Today, I came in, and he was whistling again. And let me remind you: this isn't regular whistling -- it's like someone is blaring a CD of whistling with a PA system from an Aerosmith concert. I went about my business away from the fuckface, and about an hour ago, went to use the restroom. As I go in, everything is normal; smells like someone is taking a dump, but nothing out of the ordinary for a men's bathroom. But then, as I ready myself, I start hearing the whistling. The guy is taking a massive shit and whistling like he's performing at Carnegie Hall! So, instead of finishing my business and walking out, I finish my business and, with both fists, pound 7 or 8 times on the wall of the stall. All I hear is his elderly groan, so I walk out. I haven't heard him whistling since then.

Do I need to buy this guy a muzzle??
