"Hello, I'm a Mac"
"And Hi, I'm a PC.... ow!"
"What's up, there, PC?"
"Well, I just got this shot that's supposed to keep me from getting new viruses, but it, uh, seems to be doing something else to me instead."
"Huh, that's weird. Sorry to hear it. Of course Macs don't get viruses: we're immune from all that."
"Well, that's just great, Mac, but that doesn't -- whoa... the room is spinnering..."
"Is there a doctor in the house?"
"Maybe another shot in the arm will do it."
"Sorry, we're fresh out."
