The late-night host has become obsessed with booking Caro, who's famous for his epic multi-volume biography of former President Lyndon Johnson. When Conan moved to TBS in 2010, he tried to book Caro, to no avail. He even created a Charlie Rose-style online extended interview show called Serious Jibber-Jabber with Conan O'Brien in hopes of luring Caro. “I pretty much made this thing as a bear trap to catch Robert Caro,” says Conan. “I keep getting other people who are great. But no Robert Caro.” ALSO: Conan is now feuding with Japan's Conan Town over Detective Conan.
