Bio
Kari Byron is an American artist and television personality best known for her featured role as a builder on the Discovery Channel show MythBusters, since 2003.
On MythBusters, Byron is featured along with fellow Build Team members Tory Belleci and Grant Imahara, and also assists co-hosts Adam Savage and Jamie Hyneman in testing the plausibility of various myths.
She became involved in the show after persistently showing up at Hyneman's M5 Industries workshop in a desire to get hired at his company.
On her first day as a paid employee, she was asked by Jamie and MythBusters producer Peter Rees to help out with the "vacuum plane toilet" myth, and she was asked to model her buttocks for a cast: a job which would later have her comment (jokingly) that she was hired "for her butt".
She was given a more prominent role in the show starting with its second season.
