A panda walks into a bar and orders lunch. After he has wiped the last crumbs from his fuzzy face, he stands up, shoots the waiter, and walks towards the door. The owner of the bar, understandably upset, yells "hey, panda, why did you shoot my waiter?" The panda replies "I'm a panda, look it up." So the owner of the bar grabs his handy dandy dictionary and reads: "Panda: a marsupial native to asia. Eats, shoots and leaves." Explain why this joke is funny in terms of comma usage.
The writer's use of commas denote that the panda must eat, shoot something, and then leave because of the use of the serial comma. What the writer was probably trying to say is that the panda bear eats the shoots and leaves of the bamboo plant.
