Garth & Bev S01 E09 Telephone

Something's breaking all the pots in Hoyt's hut and the potter is convinced goblins are to blame. Goblins indeed! It's the vibrations from thunderclaps that are knocking Hoyt's pots over. Grandfather Lir send the children to meet Alexander Graham Bell, who figured out sound vibrations can be used for quite a different purpose; he's just invented the telephone.
