From MSN.com's pre-game interview with Jeff Probst:
"Greg says: In the operating room I am king. One on one with someone, I'm scared to death. I'm only doing it for the adventure and the romance. Watch out. I can talk your ears off. I am hoping to play a pseudo-father, kind fatherly role to help my tribe.
Jeff says: Dr. Greg Smith, otherwise known as Tarzan, is one of the smartest guys we've ever had on the show. I told him right before the game started, 'Your biggest obstacle is your own ego and feeling you need to tell everybody how smart you are and how good at everything you are.' And if he does that, they'll get rid of him. My prediction: He's gone early."
From his CBS bio page (1/20/12):
"Personal Claim to Fame: Board Certification in General Surgery and Plastic Surgery, receiving a 1st place award for research in reconstructive surgery, playing for 'Doug Silvers & the Starliters' as an organ/pianist, 4th place as Campion Missouri State Wrestler Light Heavyweight and a marriage for 30 years to a true "soul mate."
Inspiration in Life: Tarzan, who is empathic toward nature; kind, brave, noble, "manly," and Scaramouche (the Raphael Sabatinni version) – a statesman, romantic, adventurer, swordsman and empathic toward the needs to women.
Hobbies: Art, music, adventure, entomology and primatology.
Survivor Contestant You Are Most Like: Coach Ben Wade – he seems to be a romantic, adventurer, poetic and creative.
Why You Think You'll 'Survive' Survivor: I'm of the jungle and part of nature.
Why You Think You Will Be the Sole Survivor: Other than the misfortunes of contretemps, I hope to outwit, outplay, outlast."
