disclaimer: not trying to offend anyone with this joke and its kind of a corny one but here goes...
This mexican guy is trying to cross the border and the border patrol officer says im sorry sir without a green card i can't let you pass.
The mexican guy keeps saying mi america mi america
The border patrol guy finally gives up and says, okay if you can put these three words into one sentence than I will give you a green card. The three words are Green, Pink, Yellow.
The mexican guy walks away thinking very hard about the three words, a short time later he returns and says,
The phone goes green, green, I pink it up and say Yellow.
I though it was kinda funny, actually I like corney jokes so oh well.
