Pernicious Pzepczynski needed money. Well he didn’t need it but he wanted some. So he accosted the next person who walked passed him, a nerdy and polite gentleman with glasses (apparently all victims look like this) who was minding his own business when Pernicious shouted, "Give me your wallet or I’ll beat you up!"
The frightened gentleman handed over his wallet and Pernicious thought to himself, "Wow, that was easy. If I just threaten to do something you don’t want, you’ll give me stuff." He thought he would try it again, only with a mask on just in case it didn’t work and he needed to hide his identity.
