A wise man once said... well I can't remember the exact words, but it was something along the lines of "Wisdom starts with humility". If you can't laugh at yourself than thats something you should work on. Recognising your shortfalls is the first step to overcoming them.
And another wise man said: "If someone can't take a joke - fuck it" (Tucker Max).
A little rude, but you can't be fun, honest and polite at the same time. I (like him) prefer tossing the politeness out.
