IT'S GREEN!
What's the colour of grass That sport is played on en masse? The most common colour seen - It's green!
The colour of Kermit the Frog As he sits on a log? His favourite colour, I ween - It's green!
The colour of a marble statue I've seen them - have you? If to Greece you have been - It's green!
The colour I see last thing at night As I turn out the light On the face of our Vulcan, tall and lean? It's green!
