Did your Dad ever harass you about your G.I. Joe guys, or your He-Man warriors? mine did. He would always come in when I was in the middle of an epic battle against the forces of evil whether that be Skeletor, Cobra, Darth Vader, or Lord Dredd (from Captain Power) and say to me and my friend "Quit playing with your dolls!". This t-shirt from Jinx.com has my response: "They're not dolls, they're action figures". It would make me so mad when he'd say this to me.
They ARE Action Figures Dad, Gosh!
