I find that any song can become stale if repeated too often, the less talented the performer and the writer, the more quickly an audience will tire. Humorous works are particularly susceptible because a large element of humour tends to rely upon an element of surprise, which is clearly lacking in a well-known piece. Serious pieces generally last longer, but are still capable of being over-performed, and we have plenty of threads here discussing just that phenomenon.

Some performers can wring further laughs out of a very tired song (or joke) simply because it is so stale, but it takes a good deal of talent, and nerve to try. A surprising number of performers don't realise that humour is seldom the easy option that it may appear to be.
