Thankfully radio is forgiving and when I have my pants off adjusting my underwear (as I am right now) you have no idea. Live TV however is a different animal, and this reporter may think about asking for a bathroom break next time before trying to pull this stunt.
You got to respect her ability to just power through it though. And really all the blame should be placed on the cameraman. He had to have noticed out of the corner of his eye. Wouldn't that be an opportune time to take some time or go in for a close up? (on her face...not the other thing.)
