Haven't you all worked it out yet? It's the CRYING SHOT these programmes are all about, the equivalent of the money shot in porn movies.
An example being Cowboy Builders here in the UK.
Basically the show starts with a sad, gullible homeowner who has just handed £30k in convertible currency over to a bloke with a high-visibility jacket and an Irish accent, who for this 30k has offered to build a 50k extension to their home. A week later, after he's sent an illiterate round to knock a hole in a wall and a ton of breeze blocks has been deposited in the front garden, there is a polythene sheet over the hole and Paddy has spunked the 30k at the bookies or drank it or both. Amazingly his pay-as-you-go phone number is disconnected so in despair the family has contacted Channel5.
A month later, a short blonde bird called Melissa bounds up the path to the door, vast bosoms bouncing in unison, to offer hugs to the depressed homeowner. Her accompanying builder scratches his head, says 'phwoarrrr, dunno about that' a lot and 'no way can we do that in budget'. Melissa puts a lower cut top on and proceeds to cadge free tiles, bathroom fitments and kitchen items from local suppliers only too glad to get the customary big hug after their donation and thus for a brief second have those wondrous appendages pressed into their stomach area.
The gullible homeowners are moved out for 2 weeks, while the team, bossed by Melinda, finish the job and transform the home into a modern contemporary dwelling, the envy of their neighbours.
Now the preparation for the big homecoming starts - cameras set up to catch the mass ejaculation of tears as Mr. and Mrs. Peawit gasp in astonishment at their transformed home, Melissa standing next to them ready for the group hug, having peeled an onion in advance to moisten her eyes in empathy.
You can sense the producer going 'aaaaahhhhhhhh that's better' as the camera zooms in on the lachrymose couple. "One hour's TV and 50 grand but we've got our tears, that's what the viewer wants!"
Cross this ethos over to almost every show you got on your list here, plus the damnable 'talent' shows like the pox-factor, voice etc. and you know waht Sun-reader TV is all about.......
