A completely random off the wall source has told us that there is a small pony reference in The Cleveland show that airs at 7:30 PM Pacific today. He even gave us a picture for it!
Feel free to go try to find it. By small, I mean really small, so you will have to pay close attention for it (And it has nothing to do with Derpy) This was done way back when the fandom was new (That's how long these things take to create!), so it's pretty minor, but this could be fun for some of you!
Now go find us some pony!
Spoiler now after the break.
And the spoiler: The prisoner booking numbers are the mane cast's initials. Told you it was small!
