The Baltimore Slun has reported that Best began life as a Nlordstrom store mannequin. Witnessing the horrors of capitalism, while unable to move or act, imbued them with a deep rage and crime-thirst. It is not clear as to the exact details of the phenomenon that gave Best their life, but a number of corroborating witnesses have recalled the exact moment with a startling clarity: multiple crab legs sprung from the mannequin as it jerked to life without warning, promptly destroying the store front.
It is rumored that Best emerged from a heavily wooded area carrying a bat, and walked in a straight line until they reached the Crabitat, though how he scaled the colossal crab guardian is unknown. Because of their preparedness, extra limbs, and air of mystery, Best was given a shot at batting practice, where a hitting coach remarked, "Wow, you're prepared and mysterious. Show me what you've got."
As a part of the Interviews performed in season 4 it was revealed that Forrest Best's pregame ritual is 'doing crime'. Forrest has not commented on the nature of these crimes though there is speculation that it has been involved in a long running series of shoplifting incidents of luxury clothing. Forrest has been seen sporting a number of items similar to the ones stolen, but insists that it is simply expressing it's interest in fashion, and borrowing pieces from Kennedy Loser's closet. When asked Kennedy confirmed that "Yes those were in a closet in my house. I'm not sure how they got there, but I don't think that's illegal now is it?"
