On holiday in New Mexico we were stopped at a check-point... it went something like this
'I'm sure you're American citizens'
'No, we're here on vacation, we're from England'
He looks confused.
'In that case can I see your....[pauses to think of word]'
'Yes, that's it!'
We hand them over
'Have a nice day'
'Thanks, and you'
and off we went
