Pamela Baird makes her first series appearance in the recurring role of Wally's sometime girlfriend Mary Ellen Rogers. Though Wally (Tony Dow) would rather follow the example of Eddie (Ken Osmond) and go stag to the upcoming school dance, Mary Ellen is determined that Wally will escort her to the affair. Ultimately, the plucky heroine resorts to persuading girl-hating Beaver (Jerry Mathers) to help her change Wally's mind.
