I really love it on TV when the gal with the big hair and fluffy sweater is
doing OA work with a full welding hood. Of course, with a big yellow flame
and very little oxygen, I'll just bet those big black soot stringer boogers
are just a flying.
I mean, if they would only give her a NexGen, she would at least have just a
little credibility.
