A bogus bishop nearly sneaked into the closed-door Vatican meeting of the world’s cardinals yesterday as they prepared to choose the next pope.

“Bishop Ralph Napierski” got past a checkpoint of Swiss Guards and was photographed shaking hands with Sergio Cardinal Sebastiani in the cobblestone square to the left of St. Peter’s Basilica.

But Napierski never made it inside the Pope Paul VI Audience Hall, where more than 140 cardinals from around the world were having their first formal meeting since the resignation of Pope Emeritus Benedict XVI. But he still got far enough in for them to notice his purple scarf...maybe a dead giveaway?

Way to go, Security!  TSA - take note....just sayin'
