"Tin-can man" may be an allusion to the Wizard of Oz character "the Tin Man" who's limbs where chopped off one by one with his own axe, enchanted by the Wicked Witch of the west. Each time, the limb was replaced with one made of tin until nothing was left of him but tin. Lacking a heart, he is unable to feel anything for someone he used to love, and so begins his journey to the Emerald City in search of a heart. A "tin man" still means someone without a heart. Why NickChopper didn't mention this is beyond me since he obviously caught the reference as well. You can also tie a string to a tin-can man and drag it from a car, and it will bounce along the pavement as if it had a life of its own.
