This is a joke I heard from a classmate recently. I don't know if it has ever been posted or sent as email before, but it's kind of funny...
There are three people learning English. Today they learn about "green", "pink", and "yellow". The teacher asks them to make some sentences using the three words, so the first one says, "Grass is green, roses are pink, and sun is yellow." The teacher appreciates it very much.
The second one says, "I like green, pink and yellow." The teacher comments, "Well, it is okay too."
When it's the turn of the third one, he says excitedly, "Green! Green! I pink up the phone and say, 'Yellow!'"
