Hilarious conversation with British Airways representative when trying to retrieve my frequent flyer info:

"Address on the account for verification?"
"Somerville."
"Try again."
"Woburn."
"No, try again."
"Pennylvania?"
"No try again."
"hmmm.  Cambridge."
"Nope, try again."
"That's all I've got."
"...."
"Boston?"
"You got it!"
