Last year, MILFY Weeds star Mary-Louise Parker groused to a magazine about how she thought her nude bathtub scene in the dope-filled Showtime hit was unnecessary.

Mary-Louise must have recently had a change of heart about setting fire to our parts, because on last night's episode, she outdid all her other Weeds nude scenes combined.

Puff, puff, and pass a little boob, boob, and ass, because M-L shows some skintoxicating T&A when her bar owner beau pulls down her panties, spanks her bare butt with a belt, then takes her from behind against the bar. They even get into a kinky slap fight!

As always, we've got the pics and clips up here, so you can watch Parker's man pork 'er. Look at those dimebags and smokin' ass jiggle!
