Me Talk Pretty

Three men, an American, an Arab, and a Chinese man are in a 7-eleven when a robber storms in. The robber points his gun at the American and says, If you think of a sentence with pink, green and yellow in it, I won't kill you. The American, mumbles something and gives up so the robber shoots him. The Arab doesn't know what to say and also gets shot. The robber then looks at the Chinese man who frantically says, "My phone go 'green, green', I 'pink' it up, and I say, 'yellow, yellow'"
