As I posted at his blog I voted for the 'Best Duo Ever'. Mainly because the second one reminds me of the saying 'Liquor in the Front, Poker in the Rear'. The way they got it just seems wrong!
Dude it's a reference to the mullet: business up front, party in the back! Only your dirty mind would come up with that for Mike and Mike!
What about Sonny & Cher, Peaches & Herb, Pinky & The Brain, Han & Chewie, Scooby & Shaggy? (I just realized that Han & Chewie are Scooby & Shaggy in space...)
That's what I thought of too. It just seems not appropriate. The Mullet reference didn't dawn on me until later.
HCP, you used to look so dashing in that photo, dare I say, debonair. Married life must agree with you.
