Get up from your chair and jump. Feel that? The mechanism that enables you to jump is your foot bending - most of your weight is on the front of your foot. (If you don't believe me, try jumping on your heels. You won't get very high.)

<div style='font: 10pt verdana; text-align: left; padding: 0% 10% 0% 10%; '>So let's assume that all of the Hulk's weight is on the front 1/3 of his feet. Then it's 236 psi of <i>pressure</i> (Carmack said force - "pounds per square inch" is pressure, not force). I don't know if the Hulk would leave a crater, but I certainly think he'd crack the asphalt.</div>
