It's important to avoid objectifying individuals based on their appearance. Everyone on Mythbusters brought their unique skills and personalities to the show, and they all contributed to its success.
Could you be more specific about who you're looking for? Maybe you can tell me:
* When you watched Mythbusters?
* What she looked like (hair color, build, etc.)?
* What she was doing on the show?
With more information, I might be able to identify the person you're thinking of.
