Last night, I was watching the Season 3 episode The Darkling. When I was watching the episode I kept thinking that I liked the Doctor's performance as the alter-ego Doctor, except for the fact that it looked like he was purposefully jutting his lower jaw out during each alter-ego scene. It was like he had an underbite or something and it annoyed me because I didn't understand why Picardo thought it made the alter-ego Doctor look scarier.
After the episode, I went on Memory Alpha's page on the Darkling episode and read the following:

Did anyone ever know this? I didn't even notice that he wore contact lenses!Robert Picardo used contact lenses and prosthetic teeth for the evil version of The Doctor. "There were very subtle changes in my appearance, subtle make-up changes," he observed. "I wore some interesting contact lenses that were my idea, to reduce the size of my cornea so that my eyes appear just slightly beadier. And I also wore a dental appliance on my lower teeth that I had not worn since The Howling. I save all of my prosthetics in a drawer, so I pulled out the teeth and wore them to give me a more Neanderthal, animalistic appearance."... Picardo also remarked, "I've saved my Eddie Quist teeth for I don't know, 12 or 14 years. It's nice to take them out of the drawer."
