Ice Hole
There was a competition between a team of blondes and a team of
brunettes to see who could catch the most fish icefishing. 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!"
