Sneezes and Time Travel

I was in a meeting the other day when one of the guys at the table sneezed...hard. He sneezed so hard that he actually blew his chair back a few inches. (Not hard to do when you're only four feet eleven inches tall, and your feet don't touch the floor.) Anyway, he shook his head and asked, "What happened?"

To which another guy at the table responded, "You sneezed, that's what happened. Are you okay?"

The sneezer still looked a bit disoriented. So, I piped up, "Oh my gosh, he sneezed so hard that he blew himself backward a few minutes in time." I waved my hand in front of the sneezer and said loudly, "Do you know what year this is?"
