Show them limmericks.

From what I have seen it is unlike anything someone who is learning english, even profficient users, have ever heard. limmericks and puns.
I knew someone who as in their late 30's, was from the phillipines, and spoke english well. Worked in the US, I would guess, maybe 5 years in the US?
Never heard a limmerick, I did the lady from niger. and once she got it, she laughed like you wouldn't believe.

She wanted to hear more and - well - I did mention most of the ones people can remember are dirty, especially those concerning a certain rhode Island town, but that kernel of knowledge just made her, literally light up and demand to hear them. But I was able to compare it to Billy Joels piano man, which was just as good.

Now bob at the bar's a friend of mine
He gets me my drinks for free
He's quick with a joke
or a light of your smoke
But there's some place that he'd rather be.

She knew the song, and with a limerick - beat-she just- I mean I can't describe it. :rollin

said like a limmerick, especially after you get the joke in a regular limmerick, that song is not so depressing.
