Several friends who were huge David Letterman fans sent me links to video of him showing up onstage at a Steve Martin/Martin Short stage show in San Antonio, Texas, this weekend. But when I watched it, I was nothing but disappointed as Dave did a Top Ten List about Donald Trump. As with most of his televised prepared material of the last decade, the list was tame and lame, relying four times on bad jokes about Trump’s hair. I’ve seen more biting satire in a Buzzfeed listicle.

While I’m sure the cameo was thrilling for the people in the crowd, it doesn’t offer hope that Letterman will return any time in the near future with something new and clever. Even Martin and Short look like they’re asking, “How much longer will this take?”
