I would make the best Apperture Science test subject because I have, like, a monkey brain that makes it so when I see a puzzle I physically cannot help but try and solve it. A little while ago, I was playing a game with a puzzle where you had to move a bunch of boxes around so you could reach a door on the other side of the room, and I didn't even notice the door for the longest time I just saw boxes I could move around in a confined space and went "oooo box puzzle weeeeeeeee" and started pushing things around without having any idea of what the end goal was supposed to be. Like, I wouldn't even need the incentive of "cake" I would be content with my reward being more puzzles for all eternity.
