Ref's Darth Vader Helmet

...A whistle blows and Darth Vader stands silently with a hand raised for a few seconds. The crowd and players await in mounting anticipation.
Darth Vader lowers his upraised hand an speaks:
"Skhhhr The ball went Skhhhr out of bounds Skhhhr. Blue teams' ball Skhhhr." And dramatically points to his left.

A player in a white uniform shouts "Come on! are you blind?!"
Darth Vader steps up to the player. "Skhhr .. I find your lack of faith Skhhr .. disturbing. Skhhr. Perhaps I should change the deal Skhhr to include a technical foul?"
The formerly outraged player steps back, aghast. "No. no need to do that, sir."

The player knew that these new helmets contained a record and replay tech that allowed for the review of wherever the ref was looking for the last 2 min's. There was also a rumour that they contained a transparent graphic display nearly as complex as a helecoptor pilot's giving access to fouls on players, time left, and who knows what else.
