While I have been known to "give it right back" to disgusting comments and actions from men, I have to agree with Bleeker. This is harassment and I would not put up with it for a minute. Not all guys are like this! The longer all of us let s*** like this go on, the longer they will keep doing it. Sorry, I don't ascribe to the humor them theory.
Now I know that Smurf really wanted this job and I also know that she is pretty young (well, compared to me). A firm "Stop right now... enough" might stop the comments.
And I have found it not to be a wise thing to socialize with people I work with. This doesn't mean you can't be friendly, but like I used to tell my students,"Friendly, not friends," when I would explain that they had to work with others who they weren't friends with or didn't otherwise like.
