Lol, it's even funnier as you watch the series because they have running jokes like when Kaiba smiles, a puppy dies. And So far up to episode 30 he's only smiled twice. The first time, it was when mokuba was saved and then Yami said it was creepy that Kaiba was smiling...
The second time was when a dualist foolishly agreed to play a children's card game with Kaiba (and it had a subtitle that said "+1 Dead Puppies" xDDDD)
