Hope no one believed this urban myth! It's totally bogus! "Constantly starting and stopping" does not cause vapor lock. A long drive on a hot day, which allows time for everything under the hood to heat soak, will. Besides, why is the guy "constantly starting and stopping" on his ice cream run?? And the engine didn't have time to cool down and so vapor locked?! Cooling down is what cures vapor lock.
And what is a picture of a '65 LTD and a '65 Mustang doing in a tall tale involving a Pontiac?!
I guess it's an amusing story, but some believe (and worse, repeat) these tales and thus another urban legend is born.
