"knock me up in the morning"

Posted by Dr. Ward Fredericks on August 19, 2003

When Americans first visit the UK they are taken aback by a much different language with all sorts of strange meanings. My first visit in the 60's was highlighted by an instruction to "knock me up in the morning"! Luckily, I just kept quiet and found out the meaning later -- i.e. call me or visit me again tomorrow.
Does anyone know the background for that wonderful expression?
