OK, it's probably not Survival Insurance... I found their website and happily it has an archive of all their commercials, and while they DO do spoofs (of movies mostly) they almost always include the same male actor... just to be sure I did go through the archive and didn't see the catfight spoof commercial.
And as pointed out above, since it didn't feature the cowboy guy (at least in part 1, it is a two part commercial) it's probably not Eastwood.
It MIGHT be Freeway insurance or maybe Solo Insurance (all of these are dicount insurance companies in SoCal that advertise on TV a lot), but I can't find reference to it online anywhere (not Freeway Insurance, but this commercial).
You can see I'm determined. Still hasn't reaired on tv in the past few days.
LATER: BTW, tonight at the Home Depot in H'wood there was a gal in one of the paint aisles who HAD to be a stripper or porn actress or something.... no woman with a regular job would look like she did (well, almost no woman... this is LA of course

). Maybe 5'2" and excluding her implants, not more than 95 pounds TOPS. Very thin but not emaciated.... a waist so small you could encircle it with a single arm. Tight faded jeans highlighted her small but shapely rump to good effect. Mid to late 20s age wise. Light brown straight hair with blonde highlights, average face... vaugely latina but could just be tan. A tiny, skin-tight beigeish top w/o sleeves and baring a lot of midriff. But the bit that caught my eye (you guessed it!) was the implants.... even from the distance of a long warehouse store aisle... the effect on eyeballs was magnetic.... at the first glance I thought that she was actually carrying something against her chest that just happened to be the same color as her shirt. They were HUGE.... even by LA standards.... ESPECIALLY on such a waifish figure. Some multiple of D and the cliche porno shape: round, with ridiculously upturned nipples and riding high on the chest wall... clearly in defiance of gravity and other physical laws. I kid you not that the prominent nipples were on the upper surfaces of those spheres... pointing at the ceiling far ahead of her. The closest I can compare her to in terms of overall appearance and effect would be Francine Dee... skinny with massive hard-looking round implants and with the artificiality of her breasts amplified even further by nipples far too upturned to be the work of nature. In fact, if you just imagine Francine Dee as white/latina... you pretty much have the picture of this girl.
No doubt that woman was responsible for more bulging eyeballs on the part of male customers in that store this evening than all other female patrons combined (and that's saying a lot... HD H'wood is really quite a spot for girl-watching). Of COURSE I was fascinated by her (even though that whole Francine Dee look isn't really my cup of tea). So distracted was I (you honestly couldn't NOT be) that I paid scant attention to her companion who was a little taller/thicker/more naturally built and still quite well endowed with a plunging neckline showing what was between 6 and 8 inches of probably non-manmade cleavage. But that's what I THINK the companion looked like in the fractional second glance I could spare from the primary subject.
Unreal. In every possible sense of the word.
