Particles in Motion is the third episode of The Cosby Show's eighth season which was first broadcast on October 3, 1991.


Theo prepares for his first parents' night at the community center and is worried about how to handle parents whose kids are having problems. During a parent-teacher conference, he develops a mutual attraction with a single mother named Lisa (Saundra Quarterman).

Lisa asks Theo to go out for coffee, but Theo turns her down, explaining that it would not be in the child's best interest for the two of them to get involved. Lisa agrees that their relationship should remain professional.

When Theo describes the situation to Clair, she shocks him by announcing that her clients hit on her all the time.

Meanwhile, when Rudy meets Stanley at the open house, she becomes instantly smitten with him. Stanley gets her phone number from Theo and asks her out on a date.

A jealous Kenny shows up at the Huxtable house before Stanley in the hopes of sabotaging their date.
