None of my favourite designs seem to get printed:

Over_10_Billion_Served
Cuddly_Catastrophe
Meooooooow
The_Beast_of_Jellystone
Goldilocks_the_three_Beers
Burp_Panda
Strike_Back

I guess they're too much fun and not arty-farty enough for threadless?

I wish people would take themselves a bit less seriously!
