I cannot believe that I don't remember this commercial. I must have seen this: I was an obsessive comic nerd and I owned a TV at the time...well, my parents owned a TV at the time. Granted I hated Rob Liefeld -- more of a Jim Lee fan -- so there's a chance that I blocked this out of my memory. And I did spend most of the '90s stoned.
"So Rob, have you had any formal art training?" No. And the evidence is here. And here.
