Actually, you've got it backwards. Nearly everyone wearing that avatar is being paid to do so, and only a few have ever worn simply to promote whatever it represents. Even though all it represents is a practical joke that got way out of hand. It's just a friendly jab at those who accuse high-ranking forum members of merit cycling, that's all.
And you used to think that a joke with teeth was a weird thing. 
And I guess you missed my name since it isn't on your list. I'm the one who brings the brownies, and I've yet to hear a single complaint.
You're not perverted enough for this list, it's obvious.
