"I'm crazy, but I'm not stupid"

This quote by Jackie Chan talks to the idea that although he might be eccentric or unconventional, he is still intelligent. He is suggesting that although he might do things that are out of the normal, he is still capable of making noise decisions and utilizing his intelligence. This quote might be translated as a suggestion to not judge somebody based on their behavior or appearance, as they may be more smart than they appear. It could likewise be translated as a reminder to not ignore somebody, as they may be more capable than they seem. Eventually, this quote is a tip to not judge a book by its cover, and to look beyond the surface area to see what someone is genuinely efficient in.
