12. Ring Spin (Late Night with Conan O'Brien)
When it debuted: 2008
Segment lowlight: The science of ring-spinning.
Conan doesn't often misfire. The man respects writing and it shows. Sometimes, though, circumstances, not a lack of talent will force you into a corner. During the writer's strike of 2008, there wasn't much for Conan to do.
Rather than try to hide it, he reveled in it. He added little time-wasting moves to the show like building a guest maze entrance and interviewing crew members. Our favorite-least-favorite moment from this period was his attempt to spin his wedding ring for as long as possible. He went back to the ring bit numerous times, going as far as having an MIT professor come on the show to help him maximize his spin time.
