He has an interesting channel. He verbalizes what he thinks is going on. You know right off the bat that the "V" is going to point to something crucial. What else would it mean, Versace?

If this were Revenge of the Nerds, you'd say, "Five."

Waddaya know, it is the Revenge of the Nerds.

Care to see something funny?

There are signs for puzzle. Jigsaw puzzle, crossword puzzle, something that's puzzling, for example. You could do like a Rubik's cube and make a puzzled expression, but usually the word is spelled. For this type of mechanical puzzle the word would be spelled.

Signing Savvy [puzzle]

Hand Speak [puzzle]

What are we seeing?

Signing Savvy spells "puzzle" and shows "Z" two times. How old fashion.

Hand Speak shows a single two-finger "Z" The word goes by so fast you hardly see it.

There is no legal two-finger "Z." But legitimacy is in usage. This right here is advanced finger spelling. It's legitimate because there are so many words with "ZZ." Seems odd, but it's true. Just look at 'em all. It goes way beyond "pizza" and "fuzz" and "fizzy" and "jazz."
