Girl & her boyfriend go to the pub.When it's the girl's turn to buy a round, she tells him that she's heard of a wonderful new drink he simply must try.
She returns with the usual half of lager for herself. For him, she has two glasses. One contains a measure of Bailey's, the other lime juice.

Instructions: "OK, what you gotta do is, you gotta swig the Bailey's and hold it in your mouth. And then drink the lime juice."
He looks a bit dubious, but she's very enthusiastic so he decides to give it a go.
First the Bailey's; lovely smooth, creamy, warm feeling in the mouth.
Then he takes the lime juice.
