Love Thy Neighbour - S1.E4

The Pratts, the Edisons' yuppie neighbours, stay at the mansion when they get their house renovated and make themselves a pain in the behind. Casey has hostile feelings towards them and dreams of experimenting on them, but Fred and Casey and too scared to kick them out. So Harry takes it into his own hands and scares them out of the house, but only Ike and Turner know what he did. Throughout the show Harry is carrying out conversations with ants.
