While recording The Tonight Show in Burbank, CA. Conan O'Brien had “Desperate Housewives” star “Teri Hatcher.” As a skit they were finishing a triathlon, and instead of a photo finish Conan slips and bangs his head right in front of the Max Weinberg 7. Apparently Conan O’Brien suffered a mild concussion. NBC was forced to show a rerun. But in true Conan fashion, he joked about the entire situation, "So tune in tomorrow when Eva Longoria pushes me down an elevator shaft,"-Conan O’Brien
