I'm a massive kid. I love all my old kid programs, fart and cock jokes make me laugh and I'm just extremely childish when it comes to what makes me laugh and what I enjoy seeing. But at the same time I find myself to be far more mature, and even sometimes smarter, then most people in my age-range. I'm not saying I'm a genius of course, I make silly mistakes while typing, I'm bad at math, etc etc.
But my question, is can you do all these childish things, but still seem mature to others?
