Carry On

I'm not sure it's really fair to expect us to remember the titles of all 31 Carry On films, and sort them into alphabetical order, in just 15 seconds.

If you happen upon Carry On Abroad early on, then obviously it would have to be the answer. And to be fair, if you google 'Carry On films rated' it does seem to be consistently listed as one of the best. But it wasn't one of the first ones I thought of.

Maybe you have to be a fan.
