Sometimes a movie or TV role is so memorable, it sticks with the actor through their entire career. Case in point: 'Revenge of the Nerds'' hygienically-challenged nerd Booger, famously played by Curtis Armstrong.

Booger (sorry, Curtis) is stopping by tonight's 'Rules of Engagement' (Thurs., Oct. 27, 8:30PM ET on CBS) playing himself -- yes, an actor named Curtis Armstrong who's often recognized as a hygienically-challenged nerd named Booger from ... oh, you get the idea.

So how does Booger come to meet the group? Turns out he shared a cab with Adam, who's a big 'Revenge of the Nerds' fan. And you know who was in 'Revenge of the Nerds'? Instant connection.

Bianca Kajlich plays a stripper named "Juicy" in the new film '30 Minutes or Less,' a role that's a tad more revealing than Jennifer on 'Rules of Engagement.' But her co-star Danny McBride helped put her at ease when they were filming the topless scene, even though they had to shoot it two different ways, said Kajlich on 'Access Hollywood Live' (weekdays, syndicated on NBC).

"Danny McBride is such a professional," she said of filming her risque scene with the actor. "He's such a fun, great guy and he made it totally comfortable. And it was fun." Billy Bush was a little suspicious of McBride, wondering if the film was an elaborate plot to see Kajlich nude. "Suspiciously, we actually shot it two different ways, so we had to do double the takes," Kajlich said.

Here's some news that'll bring back some Joy: 'My Name Is Earl' star Jaime Pressly is making a guest appearance on the CBS sitcom 'Rules of Engagement,' People.com reports.

The actress will play a potential surrogate mother for long-time marrieds Jeff (Patrick Warburton) and Audrey (Megyn Price). The series, which looks at different stages of relationships between men and women, also stars David Spade, Oliver Hudson and Bianca Kajlich.
