A mexican wants to gain U.S. citizenship so he puts in his application to the INS and schedules his tests.

He passes all the tests and finally gets to appear in front of the INS board. They review his resume and give him one last test.

The mexicans last test was to complete a grammatically correct sentence using these 3 words: Green, Pink, Yellow

The mexican thinks about it for awhile and finally comes up with the answer. He said...

"Green green, I pink up the phone and I say yellow"
