According to credible sources on the Internet a small Blacktip shark was found washed up in Lake Michigan.
Before all you Global Warming loons scream "Seeee, it's because of da warming" (don't get us wrong G.W is happening, but not right here) let us dissect this "tail" a bit further for you (we love doing this).
1. Blacktips (Carcharhinus limbatus) are saltwater critters
2. Lake Michigan is a filthy polluted fresh water body
3. There's no frickin' way this critter lived in these waters
Summation: Someone probably had a Blacktip in a home aquarium that died and decided to add a #3 Halibut hook as "bling" and then hucked it into the lake under cover of darkness and under the influence of a 3/4 case of Coors Light.
You will discover, as we have, that most shark killing miscreants drink Coors Light. We're not sure why that is the case, but take it from us-a credible Internet Source, that is the case.
The red nose on this guy and a fake look of concern is a dead giveaway and more than suspicious.
