About the Argentinians, the problem I have to say is not with the Argentinians but with the people from Buenos Aires, or as they are known, the "porteños" (from the word 'port"). The following jokes will, I hope, illuminate you.
Why do porteños smile to the sky when there´s a lightning storm?
Because they think God is taking pictures of them!
Why do porteños want to be astronauts?
Because they want to see what Earth looks like without them!
Why are there no earthquakes in Buenos Aires?
Because not even the earth can swallow the porteños!
What's the favourite toy of the porteños?
The yo-yo ("yo" means "I" in spanish!)
What's infidelity for a porteño?
To stop looking at himself in the mirror
How does a porteño commit suicide?
He climbs to the top of his ego and then jumps!
What's the best way of making money?
Buying a porteño for what he's worth and selling him for what he thinks he's worth!
A porteño was making love to his girlfriend. Reaching the climax she yells "Oh my Gooood!" The porteño says: "Oh, you can just call me Oscar!"
What´s the "ego"?
The little porteño we all have inside!
