The singer in that "Knocker Upper" song prefaced his performance of that song by saying that the title of that song seems to make Americans smile or laugh. He continued his remarks saying that he didn't know why that was and didn't care to know.

Well, I thought that was rather incurious of that singer, so I left this comment on that YouTube video page:

"I'm an American and I confess that the title of that song made me smile. It's partly because of the child like alliteration or whatever you all that ending. But "knocker upper" also has a bit of naughtiness about it ("knocking somebody up" means to get them pregnant.)"

And now you know :o)

I meant the fact that both of the two words ended in "er".

Joe, it occurs to me that that singer has the same first name as you do. Was that you? If so, good job (good job even if that singer isn't you).

But I want to be clear that I meant no harm by my comments. I thought that the singer might want to take a lighter approach to his prefacing remarks. I don't think Americans are laughing at English customs. [Speaking for all Americans, which certainly can get me in trouble] We just think those words are kinda funny and also just a little bit "naughty".

Which calls to mind another current Mudcat thread:
'naughty'; 'bawdy' - what else?
