jackgoodmanFor my geek award, I can't remember the alien that played the role, but it wasn't Q. It was some other evil-doer that kidnapped Data as an addition to his collection. It was nice to see the '62 Maris survives into the 24th century with brown borders intact. But interestingly enough, it wasn't graded. So guess grading companies didn't survive into the 24th century, too bad. 
Gotta love the internet - the alien was Kivas Fajo (played by an actor named Saul Rubinek) and the episode was titled "The Most Toys."
