4. Laurie and the Professor

One of Laurie's college professors ( Stephen Tobolowsky ), arrives at the Foreman home, under the false pretense of convincing Laurie to return to her classes. However, Eric soon discovers his real reason for being at the Forman house when he catches Laurie kissing her professor, and attempts to blackmail his sister with this information. Meanwhile, tired of bunking with Eric, Hyde begins searching for a suitable place to sleep around the Foreman home, and Donna is at the center of her parents' fighting, as they each attempt to win her favor by taking her shopping.
