-Twista's been doing that Finger movement for awhile, but I don't know who did it first out of him and Tech
-LOL...Ludacriss... yeah, I thought that he stole the "Throw Them Bowls" arms and shoulders movement from Three 6 Mafia...but then again, they did a song together.
-About Jay-Z being a fan of Tech, I wouldn't be surprised cause according to people who know Tech... people like Linkin Park and any other artists who are very talented and respected in the industry very much respect Tech N9ne.
