Mono
Lois discovers she has mono after a visit to the doctor. She then ends up giving it to Malcolm after her maternal instincts begin. As a result, both Lois and Malcolm are forced to spend an entire day and night together in the same room. Hal, meanwhile, is invited to all of his neighbors' parties after they know Lois will not be attending any of them.
