Gosh Ollie, hope you are familiar with a popular comedy duo Laurel and Hardy, from the 30's. I think Sir LOB mentored them back then with that catch phrase. (I know, a little in his dotage, but bear with him, we do)
I've just found out it is also a phrase used in the Mikado back in 1885. Guess that's when Sir LOB first heard it. Bless his little pea pickin' heart.
