It's blatently obvious that something other than spinach was used to produce biceps of that magnitude. My biceps are a fair size despite having never eaten spinach or taken steroids. However, that can be explained purely by the excessive amounts of masturbation I seem to do.

In order to achieve a normal looking tone though, obviously I have to share the workload equally between both lefty and righty. An incredibly large right bicep is never a hit with the ladies if the left bicep is of normal size.

It's all about keeping in proportion.
