The fifteen is the highest-numbered ball in the standard set, traditionally white with a maroon or burgundy stripe. As the final member of the stripes, it occupies the numerical end of the line and seems to have interpreted this as a position of some distinction.

It loves the camera. Given the opportunity, The Fifteen moves close to the lens and fills the frame, where perspective can lend it an imposing presence. It has begun to suspect that it may actually be slightly larger than the other balls. No measurements have been taken.
