whats the point of

Trying to sell everything that anyone would possibly buy, just trying to make a little money as best they can. There are people who buy that kind of thing or they wouldn't still sell it.

I think the phone holder is a total joke as well. The pet rock at least has some history and humor to it.

idk never understood pet rocks

A way to be flagrant about wasting money.

A pet rock does not claw the furniture or pee on the carpet. A pet rock will not run away or bite the mailman. A pet rock will not eat the steaks you put out on the counter to thaw.

A pet rock is nearly useless in regard to guarding your house or your person.

I had a pet rock named Bob, I’m still getting over the grief of why he ran away from me 😢

The point is making a lot of money from close to zero outlay.

rip offs are everywhere all the time.
BUT there are quality things and real experiences

he point sadly, is ignorant people are easy to fool
any many will happily dupe such, to get money

Pet rocks are dumb but that's sort of the point... a meaningless, useless silly thing. They've been making them for decades now.
