OK, this site amused me enough to give them free advertising
If you're shopping on the internet for t-shirts/prints to do with comics, you could do worse than this one:

They do have a great sense of humour. This is the message on the invoice page:

Thank you for your order! By buying this thing you are not only just getting something cool, you're also helping independent artists stay fed and protected from the elements. Over half of our artists now live indoors. Please keep this invoice for your records if you're into that sort of thing. Most people don't do that.

And on the confirmation email:

Thank you, thank you, a hundred times thank you!
Your order should ship in about 1-4 business days depending on whether or not it is in stock.  Expect another email
when your order ships with tracking information (where available).

****Please review your shipping address***

one last time if you would to make sure there's nothing wonky,
improbable, or inappropriate. Once an order is out the door there's not much
 we can do short of breaking into the
post office in the middle of the night, and they recently installed
a new security system. If there's anything wrong
with your address, or if you have any questions about your order, just reply to this
email!

It kinda reminds me of World of Goo in tone...
