Unaware that Indianapolis is on Eastern Standard Time and Chicago on Central Standard Time, Bob inquired at the Indianapolis airport about a plane to Chicago.

'The next flight leaves at 1:00 p.m.,' a ticket agent said, 'and arrives in Chicago at 1:01 p.m.'

'Would you repeat that, please?' Bob asked.

The agent did so and then inquired, 'Do you want a reservation?'

'No,' said Bob, 'But I think I'll hang around and watch that thing take off.'
