WABC: During these days of heightened security, proof nobody is exempt from the new rules, even Joan Rivers. She says when coming back from Costa Rica, she wasn't allowed to board the plane. "You can't be furious in an airport because they'll strip search you an that'll make everyone nauseous," said Rivers. Rivers has jokes even after what she calls a very upsetting ordeal, being detained at a Costa Rican airport because the name on her passport was suspicious.
