At one point we all were a witness to "Lin-Sanity" as Jeremy Lin swept the NBA nation with his quick emergence into the league.

Now apparently, Jeremy Lin has to prove he's actually a NBA player to the security folks at his new home in Charlotte.

The security guards at Time Warner Cable Arena actually held up Lin on his first day and even wondered what team he played for.

Lin tweeted about it and even said it happens a lot.

Of course let's give the security guards a break as it is Lin's first year with the Hornets.

Other than his current home in Charlotte, Lin has played with the Knicks, Rockets and most recently the LA Lakers.
