I remember watching an episode of Lois and Clark when I was a kid.
At some point, Superman rips a stop sign out of the ground and uses it to beat on whoever he was fighting that week. I made a mental note to the effect, “Huh. Wouldn’t the sign just crumple or bend when it struck something as invulnerable as Superman?” If he decided to use a gun against another Kryptonian, would the bullets suddenly develop the ability to inflict damage?
I promise, I am somewhat fun at parties.
Seriously, how much would Wolverine have to eat in order to regenerate the way that he does?
