TGIF for the Cube-Shaped Tennis Ball

U.S. Patent No. D498,801 to Joseph P. Cochrane
(of Ste-Therese, Canada)
for "Cube-Shaped Tennis Ball"

The Patently Silly Blog calls it "magical, beautiful, mysterious. . . " and just in time for curling season.

Thank Goodness Its Friday (and the ice is keen),
