Aha! So You are the culprit! I used to have a hat like that but it was stolen by an evil vile hat theif, stolen along with two whole bags of hats. Hats that were used by the transylvanians in my local Rocky Horror Picture Show cast. All of my lovely lovely hats gone. At least the theif did not get my Riff costume.
Hehe, cute. Did you get that on a trip to Scotland? They're everywhere in the gift shops. Walk round one and you get covered in ginger fuzz...
