If being funny is your business service, please be funny.
If that’s not your industry, and it’s probably not, use humor cautiously.
Comedians know well the sound of chirping crickets when material flops. The same goes in business humor.
I have an attorney client who is quite funny. He carefully uses one small witticism in his LinkedIn profile. He knows when someone comments on his embedded joke, the reader was paying attention.
I borrowed his example and have a small joke in the Interests section of my profile. It’s a good place to add a bit of the real non-business “you.”
Have fun. Be funny sparingly.
