Welp, it's time for STORY TIME WITH SEIGHT!
A former coworker told me a story once about not being confident in his own ability to pass a hair follicle test so he came up with the "genius" idea to take a strand of hair from another coworker and have the tester somehow pull that one out instead. At which point he obviously asked, "Well, what if they don't pick that one?"
And he said "Well I'm probably going to fail the test then?" (Ron Howard voice: He did.)
