Man and his wife are trying to spice up their marriage

So the husband comes home with a packet of flavoured condoms. He says to his wife;
"We'll play a game. I'll turn the light off, I'll put on the condom and you try and guess the flavour".
His wife goes down on him and after a few moments she calls out, "Cheese and Onion" as the husband responds,
"I've not put it on yet"
