If you watch a Cricket World Cup match played in New Zealand over the next six weeks, you may be forgiven for wondering why so many people in the crowd are wearing orange Bullseye T-shirts.

The answer is simple: if you take a one-handed catch while wearing the shirt, you could win up to $NZ1 million ($960,000).

And with the ICC World Cup less than one match old, Christchurch local Sanjay Gupta has already taken a catch, ensuring himself a hefty pay day.
