Getting ready to leave my apartment Sunday morning, I noticed some purple all over my car.  The side, the windows, the windshield.  Since it was loaded with chunks, I assumed it was either blueberry pie filling or grape jelly (that'd be a big waste of pie filling).

At first, I thought I had been pranked.  But, no, the answer was a little more strange than that.

It was bird poop!

According to Mercury News, bird poop takes on the color of whatever the bird ate.  So, if a bird eats a lot of berries, it will make its poo either red or purple.

If this does happen to you, you're going to want to run your care through the wash because it's been known to mess up your paint job.

Now ya' know!
