Forbes.com has a list of weird things you're not allowed to do at the Olympics in London.  It's kind of interesting, even if you're not going.  Here are the top six.

#1.)  You Can't Share an Internet Connection.  You're not allowed to use mobile hotspots.  And if your cell phone can put out a wi-fi signal, you're not supposed to use that either.

#2.)  You Can't Take Pictures and Sell Them.  You have to agree not to when you buy a ticket.  And if you tape something and post it on YouTube, it'll get taken down. 

#3.)  You Can't Play Bagpipes.  You're also not allowed to use whistles, drums, or rattles.  And unlike the World Cup in 2010, vuvuzelas aren't allowed either. 

#4.)  You Can't Write Something Negative Online When You're Linking to the Official Website.  According to the terms and conditions, you can't say anything that's, "false, misleading, derogatory, or otherwise objectionable."

#5.)  You Can't Pay with Your MasterCard.  When you're inside the Olympic grounds, you either have to use a Visa card or pay cash.

#6.)  You Can't Go to an Event and Hold Up a Country's Flag if They Don't Have Athletes Competing .  The only exceptions are Scotland, Wales, and England.
