No Whistling!!!

Someone in my office has started to whistle regularly. It's driving me batty. I can't stand whistling!

What's worse is that I can't figure out who it is....although, it's not like I'm going to ask them to stop. I'll just sit in my desk and stew over it.

To make things worse, the guy who I think it is sits in a desk with a guy who clips his nails every week (GAH!!!). Why must the annoying ones sit together?!?!
