Every one of the "Not Only but Also" shows that he did together with Peter Cook was hilarious and a joy to watch, the Pete and Dud conversations in particular. What will always stay in my memory, however, is the sketch where Dudley played the role of an out of work one-legged actor applying for the role of Tarzan. He and Peter Cook milked it dry in the way that John Cleese milked the dead parrot sketch. Two classics.
