It was an “I know you’re bittersweet, but what am I?” evening. The annual Netflix Is a Joke festival kicked off Monday night at L.A.’s Greek Theatre with a “Pee-wee’s Playhouse 40th Anniversary” show , featuring comics and musicians paying tribute to a Saturday morning kids’ show — or was it — that they grew up on or, in some cases, worked on. The main musical attractions were the B-52s , Devo, Danny Elfman and Puddles Pity Party, taking turns fronting a 10-piece big band led by Mark Mothersbaugh — and with Fred Armisen on drums — that nimbly navigated between exotica and some fairly fierce garage-rock. The comics performing, many of whom skewed toward the younger side of the Netflix-comedy-special scale, included Sheng Wang, Michael Carbonaro, Julio Torres and Patti Harrison.
