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."
