Can you do a derby for "Clown Dentist" t-shirt... It's hard to find a good creative t-shirt reflecting the life of a Clown Dentist especially reflecting the life of a FELINE Clown Dentist..
[repeat ad nauseum replacing highly specific life criteria with further ridiculous examples]
... All teasing aside, though, designs about the life of a female phd student as specifically catered to your taste would be a bit too narrow of a derby theme, y'know? Shirt.woot's gotta appeal to ALL THE NERDS!!1!
But shirt.woot does have hundreds of awesome designs available for print, many of which relate to academics and life! If you've got some time to kill, spend it perusing the vast and varied shirt.woot design catalogue! You never know, you might find something that speaks to you on that Perfect Design That Represents All I Am And Want To Be Forever level. And, hey, maybe an artist will see this request of yours and be influenced to create a derby-winning or daily presented design that'll accommodate your desires. Cheers and welcome to woot!
