Chapter 6: The Sock Fu of Justice, Subsection 3: Feigning Ignorance
A key component of the Sock Fu of Justice is the art of feigning ignorance. This involves pretending not to see or hear something that is, in fact, very much in front of your face.
As a master of Sock Fu, one must be able to feign ignorance with the best of them. Here's an example of how to do it:

Step 1: Avoid eye contact
Step 2: Turn up the music
Step 3: Pretend to be interested in your phone
Step 4: Deny, deny, deny
And that's it!
