In American English 'knock someone up' means make someone pregnant while in British English it means wake someone up. A British woman on holiday stayed in an American hotel and as she went to bed, she called the reception desk and said to the guy there: "Would you please knock me up at 5 in the morning?" He was embarrassed and said : "Sure, mam, it's kind of you."
Have you ever encountered an awkward situation something like this in your life?
My dad went into a shop in Italy and accidentally asked the woman if he was a Christmas tree ornament ?. He meant to ask if they HAD a Christmas tree ornament.
Who knew such an amazing service is available...lol
