OK. So, I'm a leeetle obsessed:
Here is the Chickenpants tribute to my very favorite Doctor, David Tennant. He sports a totally hand stitched suit, complete with functional interior pocket to hold his -oh yes- sonic screwdriver.
(He also has a little loop sewn into his hand, if you prefer him to hold said sonic screwdriver.)
"Jack: [incredulously] Who has a sonic screwdriver?
The Doctor: I do!
Jack: Who looks at a screwdriver and thinks, 'Ooo, this could be a little more sonic?'"
The Doctor: What, you've never been bored? Never had a long night? Never had a lot of cabinets to put up? "
You can check him out here, or check out his Flickr set for more pictures than you can shake a sonic screwdriver at.
