'The Tonight Show With Conan O'Brien'
Debut: June 1st, 2009
Lifespan: Six months
What began as a passing of the torch from Jay Leno to Conan O'Brien ended up becoming – from a publicity and punitive standpoint – one of the messiest divorces television has ever witnessed. Conan's Harvard Lampoon-tempered brand of comedy obfusticated the same audiences that previously flocked to Leno's more palatable humor. The 11:35 p.m. viewers could not grow accustomed to Conan's offbeat styling, weird cast of characters and strange dance moves, and they demanded their Leno back. So, after six months, The Tonight Show With Conan O'Brien was out, and The Tonight Show With Jay Leno was back in. We'd love to show you some of our favorite moments, but unfortunately NBC has spent the past few years deleting all evidence of Conan's Tonight Show off YouTube. Here's a legendary David Bowie clip from Late Night With Conan O'Brien instead. Watch your back, Fallon.
