Mythbusters embodied the scientific method, but I do wish they'd stopped to actually properly explain it at some point. "Writing it down" is definitely part of the process, but it's not the whole process. The whole process is what they actually did in most of their episodes:
Make a prediction
Design an experiment to test that prediction
Run the experiment and observe the results
Come up with a conclusion
Sometimes they played fast and loose with some of these steps to make entertaining TV. But, fundamentally, they were doing science.
Screwing around still covers parts 1-3 though. You say something stupid (hypothesis), your friend dares you to do it (experimentation planning), and you do it (experiment).
