'No, the plane ones..'

So we're going to this wedding tomorrow and as usual J leaves it until the evening before to get his stuff sorted. He finds out that his suit no longer fits, so off we go to get a new one.

The conversation about which cufflinks to go for became really confusing.

A "which ones do you like?"
J "I quite like the plane ones"
A "really? But you're not a war veteran.... Or in the RAF"
J "what are you talking about? I think they're nice and simple"
A "what, plane cufflinks? Bit unusual aren't they?"
J "no you twat, not the plane ones, I meant the PLAIN ones!"
A "oh right, yeah, they look good. Go with them"
