Big Wooden Balls. Literally.

I found this video charming, and oddly fascinating; but the big surprise was the utter lack of double-entendres.

Perhaps it's our culture's over-saturation in post-Michael-Scott "that's what she said" punchlines, but I hear a phrase like the one at :40, for example, and I assume the next words will be "HEY-O" or at least we'll see a wink.
