Anal Ysis.

I do have some very clever friends but, by a long chalk, my close chum Smartie has to be one of the cleverest.
Believe it or not, he can name any sweet that you'd care to come up with, just by having it inserted into his rectum! A talent that gets him invited to all the best parties.
Not long after I'd met him, and having gone through most of my sweetie tin without getting one of them wrong, I thought I'd fix his game by sneakily inserting my 'instrument of love' into him.
"Hah," I thought "pick the bone out of that one!"
After a moment of deliberation he declared "mmmm, that's a Treet!"

Well I'll be blowed (with a bit of luck)!!!
