Hypothetically speaking what would a light hearted INTJ look like?

I'm curious what my fellow INTJs would think. We know that our type tends strongly towards being seen as being very stern or serious or, dare I say, humorless. But I'm curious what an INTJ with a sense of humor might look like in your opinions?

And don't tell me INTJ can't have a sense of humor, at the end of the day, regardless of our best efforts, we are all in fact human (theoretically) so surely there is/are INTJ who are light hearted and like to joke around a bit.
