You're right, you don't know anything about sign language. Maybe you should look into it more before dismissing a dig? The fake-deaf signer neither spells nor signs the word "ALL." Plus his halting [SPACE] hand gestures [SPACE] are [SPACE] that of someone who has never signed before [SPACE].
SIGNING THE WORD "ALL":
Location: Neutral signing area in front of the body
Orientation: Palm orientation changes throughout the sign. In general, the right hand is palm out at the start of the sign and ends up palm back. The left hand is for the most part, palm back.
Movement: The right hand does all the movement in this sign. The left hand stays fairly stationary.
Non-Manual Marker (Facial expressions and or body language): Neutral, unless you are making a point that someone ate the "whole" pie or a similar inflection.
Memory Aid: Think of reaching into a bag of money and trying to scoop out "all" the money.
Interpretations: Whole, entire, complete...
Inflections: If you do the sign larger it could means things like "every bit of it" or "the whole thing."
