The Japan Tobacco Man
I can't the recall what the interviewer said to him (on the ENT set), but his reaction was to say something along the lines that if he wasn't wearing makeup, his face would be red (the interviewer's comment wasn't inappropriate, just very complimentary and it embarrassed him. The scene is pretty cute).
Yeah, i'm not sure, but i think it was because of a vid that the interviewer showed him where some fans talked about his sexyness and a part of his body.
I think it is from Trekkies 2, and there was some stuff there to turn him red.
