My in-laws had/have some good Gangster names; real and imagined and my brother-in-law and I used to make some up.
My mother-in-law (my board name MaryCas) worked at a banquet hall. She was known as "Salad Mary".
We knew this guy who was rumored to have killed his wife by slowly over dosing her. He was Johnny the Pill.
Then there was Mike Forcculo, or simply Mike Fork.
