Civic Arena ornaments in your mouth
Due to overwhelming demand (and "overwhelming" being an understatement), only the first 15,000 ornaments sold will be on Christmas trees in 2011.  They sold 11,000 of them in like 5 minutes. [ PENS ]
And judging by the above graphic we pulled from the Foundation's site at 8:10am Thursday, it looks like the 15,000-ornament limit has been surpassed. But they're still available via the Pittsburgh Penguins Foundation.
