Crewmate, but it can be a crew-only addon so that every crewmate can harness the power of dadjokes!
Normal crewmate, but everytime a meeting starts, he says a dad joke everytime at the beginning. These puns can sometimes give clues about roles in game (there is a setting), or those who interacted with the Dad.
For example, if there is an Arsonist or a Pyromaniac, the message can be
"Dad, are we pyromaniacs?"
"Yes, we arson"
If there is a Gravestone, it could be
"What do you call a typo on a headstone? A grave mistake!"
This would be less bullshit that any revealing role (because it just gives small clues), but also would be funny for some (Ex.: Myself).
If this isn't well received, I could repurpose the role into a similar thing called "Commentator" with less corny messages.
