In episode 19 of season 12 of “The Big Bang Theory”, Leonard decides to have some fun with Sheldon by swapping the stickers on his Rubik’s cube. However, Sheldon quickly figures out the trick and retaliates by giving Leonard a taste of his own medicine. Watch this hilarious prank war unfold between the two roommates in this must-see YouTube video.

The Big Bang Theory, Rubik’s Cube, prank war, Leonard, Sheldon.

  1. I know I'm just dumping some boring facts that nobody asked for, but still, I wanted to. What Sheldon said at the end, "Everything has a number if you assign it a number," has to do with something I learned this quarter in college called cardinality. It's basically the "number" of elements in a set, but you can still talk about cardinality in infinite sets, so it's not technically numbers. But what's interesting is that if you find a bijective function that goes from one set to any other set, then you just proved that they have the same amount of elements and mapped one to the other. So, Sheldon just mapped the faces in the rubik's cube to natural numbers with cardinality (and his friends to natural numbers as well lol).

  2. As someone who actually knows how to solve a Rubik's cube, there's a simple thing called parity that makes Sheldon's claim about which stickers were swapped wrong.

    If there were pieces that were itself invalid (such as an edge piece with white and yellow which are supposed to be opposites, or 2 edge pieces that are red and green), then it would only take a few seconds to figure out and wouldn't require someone be too clever.

    But if all of the pieces were still valid, then you'd be able to solve the cube 80% of the way before you'd ever notice. And you wouldn't possibly know whether 2 stickers were moved or all of them, because there's no mathematical difference.

    Anyone who actually knows how to solve a Rubik's cube (even a beginner's method) probably has experience with solving a cube with a twisted corner and having to untwist it.

  3. For everyone saying the friend thing is in order acquired and at the end of the video Leonard literally says he's number 5 so that can't be right it's probably in order of trust with Amy as one and family members such as his mum and Meemaw taking second and third.

  4. It's amazing how if you say something confidently, you can sound smart. The stickers on a Rubik's cube don't have numbers. Neither do the pieces, even.

  5. Doesn't he only have 5 friends anyway, excluding amy? I'm guessing it's in the order of when he first met them

  6. … people keep saying 4 is a ranking. I bet this is the 4th person that he felt he wanted to be friends with. So Amy will always be a higher number

  7. Those cube sequences arent real. Real cubers do the blindfolded method of abc for corners and edges. To my knowledge i have never heard of numbers being used

  8. Bet this is the order:
    1 & 2: Lennard or Amy
    3. Lennards mom or Steven Hswking
    4. Penny
    5. Raj
    6. He doesn't care past 5 because everyone else is far below him and went to a "worse" school like MIT😊

  9. An easier way to make it unsolvable is to pop out an edge piece and flip it around the other way. It creates a permanent parity error that can’t be fixed on a 3×3 cube
