I remember reading that all his close friends knew that the tune that Peter Sellers hated more than any was 'In The Mood'. At his funeral the priest announced that they would play a piece of music that Sellers had specifically asked for and which obviously meant a great deal to him. Sure enough, 'In The Mood' rang out, resulting in all his friends collapsing in laughter.

That's the way to do it - carrying on making people laugh after you've gone.
