Fishing secrets

There was a competition between a team of blondes and a team of brunettes to see who could catch the most fish ice fishing.
Once the contest started, it was clear that the brunettes were going to win, they kept pulling out fish after fish.
Soon, the blondes got worried and sent over one of their team to see what the brunettes were doing differently.
A few minutes later, the blonde comes running back. “A hole! You need to put a hole in the ice!”
