Looking for a stupid "bikini babe" comedy

I saw this movie years ago and haven't been able to find it since. I've typed every single keyword search I can think of into IMDb and even searched what little I remember from the premise on google but with no luck.

Anyway, it was likely post 2000's and I think there may have been a slight Western theme. There was quite a bit of nudity if I remember correctly. Basically there was an older man whose company was being shut down or bought out or something. I think he wore a cowboy hat. So he enlisted the help of these young slutty bimbos to raise money who frequently wore bikinis throughout. The only specific scene I remember is when one of the bikini girls was helping this Asian guy and her bikini top got pulled off by a side mirror on a car. There's a cartoonish sound effect to accompany it. The Asian guy then proceeded to stare at her boobs and the captions read "Pumpkins, pumpkins!" whenever he spoke. Pretty vague, I know, but that's the only part I remember enough to describe in detail.

It's a really stupid and poorly made movie, by the way, and I'm only wondering out of curiosity. Before I forgot what the title was, pretty sure it had a very low rating on IMDb.
