The written word is what we have.
Remember Eats, Shoots and Leaves?
A panda walks into a café. He orders a sandwich, eats it, then draws a gun and fires two shots in the air.
« Why? » asks the confused waiter, as the panda makes towards the exit. The panda produces a badly punctuated wildlife manual and tosses it over his shoulder.
« I’m a panda, » he says at the door. « Look it up. »
The waiter turns to the relevant entry in the manual and, sure enough, finds an explanation.
« Panda. Large black-and-white bear-like mammal, native to China. Eats, shoots and leaves.«
