Joan Rivers is pissed. Usually. But Joan says she was "held hostage" by airport security in Costa Rica this weekend because her passport read, "Joan Rosenberg AKA Joan Rivers," which was apparently suspicious to the agent ... even though she tried to explain it was the name of her late husband, Ed Rosenberg.

No one in the world looks like Joan Rivers (fortunately), so why would someone pretend? [TMZ] It does seem like famous people always cause the most travel trouble. Here are some other mishaps.
