So, I'm thinking the website should add a couple t-shirts to its list of cafe press gear, and I'm thinking the best way to do that (as it imposes no art-need) is to zero in on maybe two or three quotes from the books. 

The business card thing -- that's been done.

But ones at the top of my head include:

"I the hell am Harry!"

(and)

"The building was on fire
and it wasn't my fault."

(Jim's favorite opening line)

Thoughts?

"Life is a journey. Time is a river. The door is ajar."
