Sally, even in her dotage, was transfixed by Wimbledon; year after year she'd return the serves, or sit patiently waiting for a tennis ball to appear out of the side of the telly.
Jonny, a young tom (oxygen deprived at birth, & consequently not the full deck), lies sprawled over the top when the skiing is on; convinced that if he plays patty-fingers with the skiiers for long enough, something must happen. It usually does - he falls off.
Ben (also a bit of a thicket) has been known to wander around the back of the box looking for whatever was on Pet Rescue. Not interested in any other programme whatsoever.
All the rest... not interested!
