Making Fun of the Buyers
I cringe to see how the buyers are set up to look ignorant and clumsy.
"Help with the demolition." Let's give the girl a little bitty tack hammer to smash the plaster or drywall. Jonathan gets a nice big hammer.
Make the buyers carry a toilet down the stairs, always good for a laugh. They're too inexperienced to unbolt the tank from the bowl, so that doubles their task, also the comic effect. Just don't give them a clue.
