I know we have a words to live by thread and a movie quotes thread, but I hate to see this core wisdom left out. Maybe you have seen this type of knowledge on a t-shirt or spray painted on an underpass, neither of which make them less useful. I'll start this with a couple of my favorites...then y'all just have at it:
1. Never Play Leapfrog with a Unicorn.
2. Never hold a cat while cranking a chainsaw.
Just to be clear, the post does not have to contain the word "never"...just be a universal truism with a tinge of humor.
