i’ll take 3. we can be boring together

I have just the opposite reaction.

Steer clear from co-worker 1..

Really? Co-worker 4 is just repeating a pun. Using "sharpe" to mix the meanings of "good looking" and "literally sharpe" is a well known joke. Almost a dad-joke, a joke that's been done so many times that everyone recognizes when it's there to be done, but the person who actually does it out loud will annoy people with their predictability.

1 and 3 are way more creative.
