I drink booze, I smoke, and I'm hooked on caffeine. I actually have been known to swear at times and belch and even raise my voice when provoked. And I'm not physically repressed!
As tempting as it seems to wear tennis shoes with your tux, don't do it. I think it looks ridiculous. If you're 14 years old, maybe give it a shot. In general, don't portray anything that says 'I'm too cool and I don't care.'
You know looking back on it now I used the fight and after the fight as motivation, to make sure I was going to be the best middleweight in the world for a long time.
