LOL. I used to HATE the singing, when I was {much} younger. Doesn't bother me too much, these days - I'm so used to it.
One of the funniest B-Days was probably some 10 years ago or so - b/c I did something way out of my usual character. At a Texas Roadhouse on my birthday (it was the year that MP3 CD Players first came out - in my early 20's, maybe?), they actually bring out a wooden horse that you're supposed to hop up on and sit on it, as they sing Happy B-Day to you. It's optional - not every1 does it, of course. Usually, I didn't hop up on it for my B-Day when I went there - but, for some reason that day, I actually did it! Who knows - maybe I had one too many caffeinated sodas, that day!
I wish digital cams were a thang back then - that'd be one hilarious pic to have thrown up! :-x
