Oh, Don Piano

My sister sent me an email today that said, "Careful, you may pee yourself if watched on a full bladder" and cut-and-pasted a link to this video. Now, this is not an unreasonable thing for her to warn me about, because I have laughed so hard that I've peed myself more times than someone who has been toilet-trained for more than 25 years really ought to. Yes, I feel closer to you, Internet, for having told you that.

Still, even if you have a bladder of steel, you have been warned.
