I studied the ancient art of Kung FU F*ck You under Master Wholeasshole.
When I reached a certain age, I had to retire my black finger skills. It's not martial art for the young.
Now, occassionally, I use it on the highway. Only, unlike other posers who flash me the Kung Fu F*ck You finger in anger, I use my finger in helping to clear the highway of assholes. My finger actually makes them crash.
I use it sparingly and save it for those real assholes, not to be confused with my Master Wholeasshole.
Thanks for the video, but there should have been a warning.
Please don't try this at home. These are trained professional Kung FU F*ck You fighters.
