Snooker Ball Diet
"The doctor says, "Well, let's start with your diet. What kind of food do you eat"?
Man says, "I eat snooker balls." "Snooker Balls?" the Doc asks "What do you mean you eat snooker balls"?
The man replies, "I eat the red ones for breakfast. I eat the white and black ones for lunch. I eat the blue and yellow ones for dinner".
The doctor ponders this and nods his head saying, "Mmm-hmm, yes, I see. Well I think I know what your problem is".
The man says, "Really"?
"Yep" says the doctor, "Not enough greens"!
