In honor of the late,great Stephen Hawking, here's a clip of his cameo from the Star Trek: The Next Generation season six episode 'Descent, or Part 1',playing poker with Data and Isaac Newton and Albert Einstein (it's actually Data playing with holodeck simulations of the three). They discuss the curvature of space-time and Newton's apple record while Data and Isaac fold, then Hawking smokes Einstein (who was convinced he was bluffing) with four-of-a-kind, and much to Albert's chagrin. Oh,that Stephen! I bet he changed the cards in his hand with his intellect. Rest in peace.
support going for the video.
