Okay--at the risk of being a little coarse, here's one for ya-- and it would definitely be a conversation piece!

Yupper-- You can indeed get a walking stick made out of a bull's 'organ'!
Their use seems to have evolved somewhat,as I read once that in the olden days they used them originally as flogging instruments! Yipes!(Talk about using every part of the animal, letting nothing go to waste!)
My dear departed Dad used a bull's 'pizzle' walking stick for years! The whole notion of it fit perfectly with his oh-so wickedly British sense of humour-- It was hilarious!
And yes, as it claims in the ebay ad,these do look like real "wood".! And they're sturdy, too!
