Insert foot here.

I was out with a friend last night who is smitten with a new girl.
Last week, I went out with him on their first proper date to play chaperone.
I ask how it went after we left them to their own devices,
He says 'fine, other than a couple of teething problems',
'Like the psycho husband...' says I, joking.
'How did you know!?' he says, seriously.
