Once upon a time long, long, ago there was a season when neither the Packers
nor the Vikings made the post season playoffs. It seemed so unusual, that
the management of both teams got together and decided that there should be
some sort of competition between the two teams because of their great rivalry.
So, they decided on a weeklong ice fishing competition. The team that catches
the most fish at the end of the week wins.
So on a cold northern Wisconsin lake they began their contest.
The first day after 8 hours of fishing the Vikings had caught 100 fish and
the Packers had 0.
At the end of the 2nd day the Vikings had caught 200 fish and the Packers 0.
That evening the Packers coach got his team together and said, “I suspect
some kind of cheating is taking place”, So the next morning he dressed one
of his players in Purple and sent him over to the Viking camp to act
as a spy.
At the end of the day he came back to report to the coach. The coach asked
“Well, how about it, are they cheating?”
“They sure are,” the player reported, “They’re cutting holes in the ice”.
