Corrected entry: In the final minutes of the episode, Henry and Wendell Deaver are playing chess. Henry makes an incorrect move with one of his Knight pieces to take Wendell's Knight. He then announces that he has Wendell in check. Henry's other Knight was in the correct position to make the same move, legally, and remove Wendell's Knight from the game.

Correction: Henry doesn't move his Knight, he moves his Bishop diagonally to take Wendell's Knight. Henry's Bishop now has Wendell's King in check.
