Something you say to a guy with their flys down.
Amusing to time how long it takes them to work out what you're talking about. Perhaps you could keep score in a blank notebook.
Also good for people who like birdwatching as it links into the 'nuthatch' as a species.
Me : 'Your nuthatch is open by the way'
Him : 'What?'
*Looks around for birds of the nuthatch variety.. eventually lands on open flys. *
*Continues to look confused*
*Carries on being confused*
Me : 'Your flys are undone you fool!'
