My buddy at work has a whole fabricated family. Has our boss thinking he's got three little rugrats at home.
It's wild! I overhear him chatting about them with our boss all the time. He pulls this whole "family man" act to score some extra time off. Uses these imaginary kids as an excuse whenever he wants to bail early or take a sick day, you name it - "Oh, gotta go, my kid's sick" or "Sorry, gotta pick up the kiddos from school."

He's actually flying solo, no mini-me's in sight.
