Ok here is one that I've heard...
While I was attending the Joe Kubert School a mate of mine was telling me how he had met Liefeld at a convention. He had walked up and asked Liefeld to sign his book or somesuch. Anyway as he is standing there he asks Liefeld "So what did you do before you started doing comics?"
Liefield: "Eh..I delivered pizza"
To which my friend replied " Oh." with a slight nod of his head. Suddenly Liefeld exploded at him
Liefeld : "WELL WHAT THE HELL DO YOU DO THEN!"
My friend, shocked at the outburst and still a student stammered out " ahh..ahh.. Im unemployed at the moment Sir..." To which Liefield laughed and continued with a point of his finger
Liefeld: "HA! YOUR A LOSER!"
Now again, my friend SWEARS that its true, but even if it isn't the thought of Liefeld freaking out on someone like that is still funny as hell to me.
