This isn't even funny, just cringy.
Last week I was waiting by a taxi rank and there was a man next to me, standing quite close. The cab driver finished his fag and came up and said, 'Where are you two going?'
Man: Oh, we're not together.
Me, in failed attempt at humour complete with freakish dramatic eyebrow wiggle in Man's direction: I should be so lucky!
Man: 
I think he thought I was trying to pick him.
I so wasn't. I have no idea why I thought that would be funny. I am not Benny Hill IRL, honest.
