Geek/Nerd: Dr. Jack Hodgins
Actor Name: T.J. Thyne (Thomas Joseph Thyne)
Year of Birth: 1975
Fun Fact: More later...
Dr. Jack Hodgins, better known as one of the squints on Bones, is your scientific nerd. Hodgins, as he is called on the show, is an entymologist and gets his kicks out of dirt, molds, and numerous bugs. The delight on his face gives one the creepy crawlies. He also reminds me of the The Lone Gunman from X-Files with his attention to conspiracy theories.
It was the beginning of the third season, when he and coworker Angela Montenegro got together, that I began to see the actor as being in any way attractive. Compare the scruffy looking guy in the first picture with the smooth character in the second picture. Although I think T.J. Thyne may be growing his hair out again, I will never look at the guy the same way I did. Those eyes are gorgeous.
Those conspiracy theories may filter over into real life as there is nearly nothing on his personal life and thus a complete lack of fun facts. Check his IMDb though and see all the shows he's been in.
