During one Tonight Show taping Conan had to stop the show for a moment, and address the audience, pleading with them to please stop booing every time a particular guest’s name was announced. (They’d already booed when the warm-up said this guest’s name, and again when Conan teased them before throwing to commercial.) It was the only time I’ve witnessed this, in over 13 years on late night. That guest? Spencer Pratt.
