Say what you will about Weeds' Nancy Botwin (Mary-Louise Parker), but she's not one of those women who miss opportunities for being timid. In Monday's episode she wanders into a "podunk bar," encounters guest star Mark-Paul Gosselaar, spends a few minutes looking him up and down and then moves right on to the dirty deed. We can't show you the second part of that story (you need Showtime and your parents' permission for that), but we do have an exclusive sneak peek at their sparking sexual tension. Press play above to see it for yourself, and then be sure to tune in for the explicit stuff when this ep airs on Showtime Monday, Oct. 11 at 10 p.m.
