This tee-shirt is absolutely silly. I admit it. I'm a writer, not a designer. (The circle is supposed to represent the glittery naval ring that alternative-universe Alkelda wears while fighting space-pirates. It's her lucky naval ring.)
Just because I'm not an artist doesn't mean I don't know artists. I'd probably don a Blogapotamus Rex tee-shirt if someone were inclined to create one. It would probably have a nifty cartoon on the front and something clever underneath the picture.
Now, I'll see if Galatea takes the bait...
Addendum: Yes, she took the bait.
