In this scene Constanze is given a penalty (showing her legs to the crowd) for losing a game, and according to Peter Shaffer the inspiration behind this scene was drawn from a real event, although it was actually quite the opposite situation. Around April 1782, when Constanze and Wolfgang were already officially a couple, a little incident happened: as a penalty during a parlor game, Constanze let a young man measure her legs (which, of course, was then considered highly inappropriate, especially for a young unmarried lady). When Wolfgang learnt about it, he wrote his fiancée to voice his disapproval: "... Why in the name of heaven did you not take the ribbon and measure your calves yourself? [...] you have allowed it to be done to you by a stranger with whom I have nothing to do." Apparently, Constanze didn't take the reprimand too well and temporarily broke off the relationship with Wolfgang (judging from Mozart's own letter to her: "You told me to my face that you intend to have nothing more to do with me. [...] Surely you do not hate me so much that I may be your friend no longer and you - no longer mine?"). Fortunately, the engagement was resumed when he apologized and offered to put the whole affair behind them, and they got married a few months later.
