Well, it was a light-hearted episode. Obviously they could have come up with a better lizard man costume. You could see where the zipper was on the back of the suit. I don't see why they didn't just use CGI for the lizard man. The lizard man explaining himself as to why he did the things that he did didn't help the situation either. That was a major suspension of belief for last night's episode. Seeing Mulder scream like a girl was funny though.
