The story goes that Milton Berle never actually pulled the entire length of his penis out of his pants. He only used just as much as was necessary to prove that he was longer than whomever had challenged him to a (literal) dick-measuring contest. This is an interesting idea because it points to a seemingly contradictory exercise of restraint in relation to something that is, in the most basic terms possible, the ultimate assertion of masculinity. Ultimately, it's about confidence: Berle only pulled out as much as he needed because he had no desire to do anything other than prove his supremacy - he was already secure in his position as the biggest wang in Hollywood and needed no conspicuous display in order to solidify his reputation in the matter.
