Emmitt Smith, One of the Eight Witnesses?

After church today I asked Aim and Stephen if they could name the Eight Witnesses to the Book of Mormon. As a hint, I told them there were three Smiths. It didn't take long for them to pick out Joseph Smith, Sen. and Hyrum Smith, but they got hung up on the third Smith. Then suddenly Stephen's face lit up and he said "Oh yeah, Emmitt Smith." Aim and I busted out laughing. Stephen, realizing his mistake corrected himself.  "That's right. Emmitt Smith was Joseph Smith's wife." Aim decided to correct Stephen on both of his mistakes. She told him "Emmitt Smith was a football player who used to play for Florida State."

I don't know which answer was more disappointing. Stephen thinking Emmitt Smith was one of the Eight Witnesses or Aim thinking Emmitt Smith was ever a Seminole.
