You cannot bore us with this question. Thought I would say that this question is not a tremendous amount of fun, but a tremendous amount of pain. :)))) Funnily, 18, I can play, 12, also. 1 most probably. But 6, I cannot. :)
If one only, it would be my Rolex 6542. But 6... Well, it is a torture! 
Best,
