I realize at on level this is meant as a joke

To the engineer there is an even more important lesson to be learned.
Make sure that you understand the symptoms and their route causes. Many
times we make the error of treating a symptom "car will not start when
vanilla ice cream is purchased" therefore the car is allergic to vanilla
ice cream.

Instead of understanding the reason for the symptom - vapor lock.

I had a challenge about 9 years ago where the solution for a part
pulling of
a bar was to hold it tighter. Actual reason the part came off the bar
was that the bar rotated when pulled so that the part to be pealed off
the pins, it never once actually tore off the pins. Solution was to
change shoes for the bar so the bar rotated to prevent pealing the part
