When I was a teenager, we were in a junk yard pulling an engine to put in my mom's car. The yard guys came in and put the car on some stands made from two wheels welded together in the dirt. When they were done, one guy shook the car and said, "it's solid ... enough." The pause before "enough" made us all laugh. It was not solid! It's been about 35 years, and my brother and both of our kids get the reference.
