How about this: the scene is Michael entering Roth's home in Miami. Roth's wife tells Michael that it's okay and asks him if he wants a tuna sandwich. Michael says no and then starts walking toward Roth's tv room. As he does, look at Michael's left hand which would be on your right. Michael folds his two inner fingers into or near his palm while holding his two outer fingers relatively straight toward the floor.

Is Michael a Texas Longhorns fan? Is he an Illuminati? Is he giving the Italian Coma?

I seem to remember his employing that sign in another scene.
