Alpha Centauran Table Tennis Club
From Tardis Wiki, the free Doctor Who reference
The Alpha Centauran Table Tennis Club was a club established by the Alpha Centaurans for the play of table tennis. The species was naturally gifted at the game, since they possessed six arms.
The Doctor was a member of the Club by his fourth incarnation. (TV: Robot) He kept his membership card for many years, and his tenth incarnation still had it. (PROSE: Forever Autumn)
