Instantly the first thing that comes to mind is my dad. His nickname throughout his whole life has been Sneaky Pete. Ask anyone in the bronx. haha.
My mom actually bought him a powder blue shirt in the late 1970s while they were dating. Then she ironed-On letters to spell out “SNEAKY PETE” on the front. That was my inspiration. He’d kill me if i posted the pic of him wearing it (and his sweet bell-bottom pants). ;)
