Ice Hole

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!"
