My first joke that ever aired on 'Late Night' was for a list of 'Top 10 Least Popular Summer Camps.' My contribution - 'Camp Tick in beautiful Lyme, Connecticut' - squeaked in at No. 10. Like a trip to Camp Tick, my time at 'Late Night' faded into memory like a short session at a dicey summer camp.
