On Wednesday, January 10th, I got a call from Sir John Hargrave of Zug.com. He was putting together a secret team of men to help him carry out an ambitious plan.

After swearing me to secrecy, he laid out the details.

"Are you familiar with the Caltech halftime show card prank?

I was. Hundreds of large colored cards were used by cheerleaders at the Rose Bowl to form giant words and pictures across the audience. Pranksters from Caltech (not one of the schools at the football game) had switched up the audience directions, changing one of the designs to say CALTECH. This was in front of a national television audience, and is considered by some to be the best college prank of all time.

Something similar was done in 2004, at the annual Harvard/Yale football game:

John continued. "I'm going to try something similar... at the Super Bowl."
