A panda walks into a cafe. 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 and sure enough, finds and explanation.
Panda: Large black and withe bear like mammal, native to China. Eats, shoots and leaves…”
So punctuation really does matter, even if it is only occasionally a matter of life and death.
