I can't bear 'Friends' or 'Sex and the City' for the same reason. I've sat down to watch them innumerable times, thinking 'I should give this a chance' and I have to switch them off within a few minutes. Now Bilko and the Simpsons are absolutely brilliant, and the cultural chasm doesn't seem to be a problem. Futurama would be another example, though it's not on the list.
