The son of a friend of mine is a colo-rectal surgeon. Having reached the heights of being a consultant now, he doesn't have to look up people's bottoms, but has minions to do the ...erm... dirty work for him. My then 10-year old ex-step-daughter (work that one out!) heard about this, and asked him, "Are you a bum-doctor?" to which he replied, "No - I'm a very good doctor!"
