From Stephen Fry in America:

There is one phrase I probably heard more than any other on my travels: ‘Only in America!’

If you bear a Briton say ‘Tch! only in Britain, eh?’ it would probably refer to something that was either predictable, miserable, oppressive, dull, bureaucratic, Queuey, damp, spoil-sporty, or incompetent – or a mixture of all of those. ‘Only in America!’ on the other hand, always refers to something shocking, amazing, eccentric, wild, weird or predictable. Americans are constantly being surprised by their own country. Britons are constantly having their worst fears confirmed by theirs. This seems to be one of the major differences between us.

And here is Fry at an Alabama/Auburn football game:
