Parker Brother's Merlin game has been seen in an epsidode of My Name is Earl (season 2, episode 18: 'Guess Who's Coming Out of Joy'). When Randy goes back home, he finds his Merlin game from when he was a kid. After declaring "Merlin... we meet again. I been practising my tic-tac-toe for just this day my friend," he proceeds to play the game.

Thanks to Haku from the forums for pointing this one out.
