"Which Gate?" joke
At the airport for a family holiday, a man and his family settled down to wait for the boarding announcement at Gate 35. Then they heard the voice on the public address system saying, "We apologize for the inconvenience, but Delta Flight 570 will board from Gate 41."
The man and his family picked up their luggage and carried it over to Gate 41. Not ten minutes later the public address voice told them that Flight 570 would in fact be boarding from Gate 35.
So, again they gathered their carry-on luggage and returned to the original gate.
Just as they were settling down, the public address voice spoke again:
"Thank you for participating in Delta's physical fitness program."
