“Never play Uno with a Mexican. They take all the green cards”

A joke about the card game Uno has been printed on many images:
 
Q: Why can’t you play Uno with a Mexican?
A: They steal all the green cards.
   
The politically incorrect joke was posted on Twitter on April 28, 2008.
 
     
Wikipedia: Uno (card game)
Uno (/ˈuːnoʊ/; from Italian and Spanish for “one”) (stylized as UNO) is an American card game that is played with a specially printed deck (see Mau Mau for an almost identical game played with normal playing cards). The game was originally developed in 1971 by Merle Robbins in Reading, Ohio, a suburb of Cincinnati. It has been a Mattel brand since 1992.

Official Rules
The aim of the game is to be the first player to score 500 points, achieved (usually over several rounds of play) by a player discarding all of their cards and earning points corresponding to the value of the remaining cards still held by the other players.
 
The deck consists of 108 cards, of which there are 25 of each color (red, green, blue, and yellow), each color having two of each rank except zero. The ranks in each color are zero to nine, “Skip”, “Draw Two”, and “Reverse” (the last three being “action cards”). In addition, the deck contains four each of “Wild” and “Wild Draw Four” cards.
 
Wikipedia: Permanent residence (United States)
United States lawful permanent residency, informally known as green card, is the immigration status of a person authorized to live and work in the United States of America permanently. Green cards are valid for 10 years for permanent residents, and 2 years for conditional permanent residents. After this period, the card must be renewed or replaced. The application process may take several years. An immigrant usually has to go through a three-step process to get permanent residency that includes petition and processing.

Why Can’t mexicans play Uno? Because they would steal all the green cards
Best Answer:  The Uno cards are yellow red and green. Green cards in real life show someone is a permanent resident. Get it? It’s a joke about Mexican aliens trying to gain citizenship.
