The Taco Bell Chihuahua and a few of his canine stars took a trip to
Tijuana. They went to a doggy bar and got a bit drunk. As they crossed back
into the United States, the border guard stopped them. 
 
"Nationality" he said to Lassie.
 
"Aamerrricannn" slurred Lassie.
 
The border guard waved Lassie through. The guard asked each of the other
three Hollywood dog stars the same question and waved them each through.
When it was time for the Taco Bell Chihuahua to pass, our  little star
showed the guard his green card while wobbling from side to side. The guard
studied it carefully and asked some questions of the tipsy star. 
 
The border guard was still suspicious so he said "I'll let you pass if you
can use three words in a sentence."
 
"No problem, senor" our little star replied.
 
"Okay, use green, pink, and yellow in a sentence."
 
The Chihuahua thought for a moment then said "The phone, it goes green,
green, green, I pink
it up, and say yellow!"
