It's always 1 to 6...

It is five.

1 to 6 is 5

15 to 20 is 5

5 of course is 5

5 is never 21

A flying 5 would be a high-five, perhaps?

The answer is a dice....

So there you have it :wink:

GT, I like your answer. You wrote, "A flying 5 would be a high-five, perhaps?"

Turn a 5 over and you have a 2.

However, another answer given by Topskip, who could be mistaken for Johnnie Mack is equally valid. :wink:
