Phyllis is named after legendary Vegas entertainer Phyllis Diller. She attends Thanksgiving at The Tanner House with her parents and siblings. Phyllis sleeps in Ramona's room along with her sister Joan. Phyllis and Joan play dress up with Ramona's clothes and make-up without her permission. The Gladstone Four jump on D.J., Stephanie, Jackson, Max and Ramona as they are about to go to bed on the inflatable bed in the living room.
While D.J. and Matt prepare Thanksgiving dinner, Phyllis, Joey, Ginger Danny, Jesse, Stephanie, Becky, Kimmy, Jackson, Ramona, Max, Tommy Jr., Fernando, Nicky, Alex, Jimmy, Jerry, Joan, Lewis and Cosmo are out playing football.
Phyllis sits at the children's table for Thanksgiving dinner.
Phyllis arrives with her father and siblings on their way to Disneyland. Phyllis and Joan tease Ramona about her dancing then roll her up in a rug. Phyllis and Joan help Lewis and Jerry sticky-tape Max to the back of his bedroom door. Phyllis listens as Jerry reads Max's diary.
After Joey gets tough with all his children by announcing they will not be going to Disneyland unless they behave, the Gladstone Four start cleaning house and Joey.
