Whenever someone says the phrase ‘you two’, or ‘you too’ in general conversation, I immediately respond as if they are referring to the band U2.
e.g. “I need you two to come help me move this filing cabinet”
“I’m not sure you’re going to be able to get hold of Bono and the gang to help you with that”
It’s not funny for me or them, but the momentary confusion into annoyance created is great.
You’d also be surprised how often that phrase crops up when you’re tuned in to listening out for it.
