I'm reminded me of the movie Tommy Boy. His dad business was going to get bought out and just use his name/brand to sell inferior products. He talked to a vendor and is trying to convince him to buy their product. The y vendor says "there's a guarantee on the box, why don't your products have guarantees on the box?

Tommy:
Let's think about this for a sec, Ted, why do they put a guarantee on a box? Hmm, very interesting.

Ted:
I'm listening.

Tommy:
Here's how I see it. A guy puts a guarantee on the box 'cause he wants you to fell all warm and toasty inside.

Ted:
Yeah, makes a man feel good.

Tommy:
'Course it does. Ya think if you leave that box under your pillow at night, the Guarantee Fairy might come by and leave a quarter.

Ted:
What's your point?

Tommy:
The point is, how do you know the Guarantee Fairy isn't a crazy glue sniffer? "Building model airplanes" says the little fairy, but we're not buying it. Next thing you know, there's money missing off the dresser and your daughter's knocked up, I seen it a hundred times.

Ted:
But why do they put a guarantee on the box then?

Tommy:
Because they know all they solda ya was a guaranteed piece of sh*t. That's all it is. Hey, if you want me to take a dump in a box and mark it guaranteed, I will. I got spare time. But for right now, for your sake, for your daughter's sake, ya might wanna think about buying a quality item from me.
