I wasn’t feeling very well so I went to my doctor.
Doctor: Are you eating a good diet?
Me: Yeah, I eat snooker balls.
Doctor: Snooker balls!!!
Me: Yeah, yesterday I ate three reds, two yellows and a black.
Today I’ve had a brown, four pinks and a blue.
Doctor: Well there’s your problem then. You’re not eating enough greens.
I'll get me coat.
