Famous last words:
Immortal words uttered by Jim Kelly (Williams) in Bruce Lee's Enter the Dragon just before his last fight and following demise after being told by Han that leaving the island is not an option.
The line entered common usage probably due to the nice flow of the words, and is used today to express one's disbelief of the what the other side just said. Also of great utility when critizising the contents of a bad node.
Although this wu itself might be seen as a prime candidate for the line, the line was too good, and is too much in common use not to be noded.
