Wallace and Gromits Cracking Contraptions. 7 The Tellyscope

To activate the TV set without leaving his chair, Wallace launches a tennis ball into a hole in the wall. It triggers a mechanism that extends the TV across the room on a telescoping shaft, so that Wallace can reach the on/off and channel buttons. When he accidentally tunes into the wrong program, he finds that he has no more balls available; Gromit hands him the TV remote, but he throws it into the hole instead of using it normally. The remote jams the mechanism, causing the TV to shoot across the room and pin Wallace to the wall.
