When the Swabian League (whom the peasants were rebelling against) later besieged the city, Magdalena repeatedly mooned the forces (front and back, actually), exhorting the armies outside the gates to kiss her arse. (2/3)

Magdalena fled the city when the rebellion ended, was captured, and nearly executed, until powerful friends had a word. For the rest of her life she couldn't run a bathhouse, go shopping in public and could only meet others at church. Worth it though, I'm guessing.
