Famous quotes about getting old getting old

I use the personalized Google page daily and I find it quite useful. (Check iGoogle to setup one yourself.) I've collected all kinds of widgets on the page, news and comics and there's even one showing me a daily famous quote.
Today's famous quote was by George Burns:

"You know you're getting old when you stoop to tie your shoelaces and wonder what else you could do while you're down there."

, which is quite funny, but it made me come up with my own version, too.

"You know you're getting old when you see the famous quote by George Burns about getting old and tying your shoelaces and all you can think is why George doesn't come up with any new material any more."
