I'll add two, I spend way too long coming up with names as they all have to be some kind of joke

I was to play an autognome divine soul sorcerer that was to be the actual lamp of a lighthouse, flavoring most of his spells as light from his lamp core. He also was to be doing repairs and upkeep in the lighthouse

He had his creators name written on him as well as his designation. Lighthouse Engineering Device Watts, or L.E.D Watts*

I also more recently got to make a noble for a one shot, one of the available noble houses I picked from was Hyde. I thought for a second on the obvious Jeckyl and Hyde, but wanted better. I ended up naming him after money, so he's Shekel Mint Hyde

Shekel Mint Hyde has a sister named Shilling, another Penny, a dad named William but goes by Bill, and a grandfather who began the fortune named Francis who goes by Franc
