Surprised this wasn't posted yet (usually the precursor to someone pointing out that it has been...), but comedian Dick Martin died at the age of 86. This year would be the 40th anniversary of Rowan & Martin's Laugh-in debuting on national TV.

I was pondering recently the demise of comedy duos such as Rowan & Martin, but also The Smothers Brothers, Jerry Lewis & Dean Martin, etc. I can't think of a single comedy act that's a duo. Perhaps it's due to the demise of the nightclub circuit. Are there still comedy duos anymore?
