Yes, Dear (2000)

Episode Overview

After Dominic returns from a sleepover with head lice, Jimmy and Christine are so anxious about Greg and Kim's judgment that they decide to keep the situation secret. They isolate Dominic while treating him, but Jimmy accidentally transfers the lice to Sam when he affectionately ruffles his hair after Dominic. Once Sam begins to itch, a guilt-ridden Christine confides in Greg and Kim. The lice quickly spread, infecting both Greg and Kim, who then unknowingly pass it to Mr. Savitsky during a hat fitting. When Greg attempts to explain the situation to Savitsky, a mix-up leads Savitsky to believe he infected Greg—until Jimmy steps in to clarify.
