Do not give out any personal information. This is like do you have a girl who cries at the smallest inconvenience? Do you have someone who is a parent and that alone is now their personality? Do you have a guy who you hide from Monday mornings so he doesn’t tell you about the fish he caught on Sunday that was THIS BIG!
Keep it light hearted!
Had a coworker that was the weird bigfoot man. Every time he came to the main branch it was a whole lecture about bigfoot. He even gave marketing a recorded speech he did about bigfoot for a local bigfoot convention and demanded they publish it internally. When he retired they put bigfoot on his retirement party cake.
