Family Ties - Season 6 - Eps 24: Sign of the Times
While Alex prepares little Andrew's resume for future kindergarten elections, Elyse proudly tells the family that Andy has been chosen as "Buddy for the Day" at school, which means he will be responsible for showing a new classmate around. The new student, Josh Richards, turns out to be deaf. Accompanied by his mother, Josh is introduced to Andy by Andy's teacher, who explains that although Josh can't hear, he can speak by signing with his hands. Tentative at first, Andy leads Josh off to "show him the ropes", telling his curious classmates about Josh's deafness and his ability to sign.
