The Hot Air Balloon Joke

Realising he was lost, the man in a hot air balloon reduced altitude and spotted a woman on the ground below.

As he descended further he shouted over to her, ‘Excuse me, please can you help me? I promised a friend I would meet him an hour ago but I don’t know where I am.'

Because the woman wanted to help she explained, 'You are in a hot air balloon hovering approximately 30 feet above the ground. You are between 40 and 41 degrees North latitude and between 59 and 60 degrees West longitude'.

'You must be an engineer' said the balloonist.
