Upper left: Sherlock Holmes Upper right: Inspector Columbo Lower right: The Detective of the video game „Disco Elyseum“
I don’t know who‘s the guy on lower left.
If you don’t know Columbo or the game, I recommend both. Best go in without much knowledge about them. It will be fun.
A Long time ago, there was a sub called /r/onetruegod or something like that. They shopped the head of Nicolas Cage on every person on photographs.
A similar subreddit did that with the head of scary bilbo from The lord of the rings. (The scene were he sees the ring around Frodos neck). They shopped the face on people in porn or on pretty women. Don’t ask.
