Think you're 'ard? You ain't got nothing on The Boss, pal.
How 'ard is The Boss? He had four teeth removed just so he could continue smoking with his jaw clenched. Oh, and in case people didn't pick up on that, he removed all the flesh from his head so they could see clearly. It's rumoured he did so using those razor blades in his bunnet.*
That's how 'ard, Howard.
*Bunnet does not contain actual razor blades. That would be silly.
