Been There, Didn't Do That - But Still Got the T-Shirt

Last summer, I visited San Francisco, including Alcatraz - the infamous former maximum-security prison. As a memento, I got an Alcatraz T-Shirt.

Yesterday, I visited the local Borders while wearing said T-Shirt. Someone came up to me and said "Those three that went missing - do you think they survived?"

I looked up at him. "Huh?"

"The three who swam out of Alcatraz - do you think they escaped, or did they drown?"

"I have no idea."

"Oh, OK - I thought you were an expert on the subject."
