This sounds fun

You're out for a nice cruise on the lake. You motor along enjoying the fine weather. Suddenly you are struck in the head by 100 pounds of frightened carp.

Kind of spoils the day, doesn't it? Well, it may happen to the Great Lakes. Non-native carp species are moving up the Mississippi River toward the Great Lakes.

Apparently, the fish were being farmed in Arkansas and escaped when flooding occurred. What in the world would anybody farm carp for?
