Maybe this question has been answered before. Maybe I'm just dense today and can't see whats right in front of me. I'm new here and I'm new at being BBC, but I grew up with a father who was bald from the age of around 21 or 22 (he never referred to himself as being bald, but rather as his friends as being hairy), but I never heard of a reference to SLY. Please help me to understand where the reference comes from.
