Or you say something and start laughing
and realise, almost in slow mo, you can feel the ha-ha - ha falling out of your mouth whilst your brain jumps up and down frantically trying to get your attention, saying 'it really wasn't that funny. Or funny at all. Now would be a good time to stop laughing'

or the awful speaking at the same time
and doing the stopping/starting thing, until you're both left with nothing to say except smile awkwardly

I rarely get that
but the inappropriate laughing and/or inappropriate talking of bollocks, oh definitely.
