Where did this joke [about Sears in TV shows] come from?

My mistake. There was a transistor and a couple of resistors there, and the resistors were printed circuit elements. It was the diode that was in its package and glued on to the board. Here’s a photo:

Thanks for the link! I’ve been wanting to look over the old catalogs for some time.
I remember once on Sanford and Son, Aunt Esther was given a bottle of wine. She looked at the label and read it in a French accent, “From the vinyard of J.C. Penny.”

The only Sears-related joke I can think of is “Where’d you learn to drive, Sears Driving School?”

Am I imagining this? Apparently they do/did have driving schools, but Sears was a perfectly cromulent store for us so it wasn’t clear why this would be automatically a bad thing.

My mom bought all my clothes from Sears. Their catalog offered a much better selection. We bought a lot of stuff from Sears.

It was good quality merchandise. You could often see the difference in quality compared to Walmart.

My last big purchase was a flat pack storage shed in 2014. A small one for garden hoses and the lawn mower. Several stores carried it. Sears had a competitive price and I ordered it from the web site.

In the Frank Zappa song, “Camarillo Brillo”, Frank asks the question “Is that a real poncho . . . I mean, Is that a Mexican poncho or is that a Sears poncho?”

We always found that funny and despite the fact that Sears has generally good quality products, we quickly began using this as a way to demean something that was not authentic or high quality.

Ex: “Is that a real guitar, or is that a Sears guitar.”

Unless your dad or older brother had copies of Playboy hidden around the house, the Sears catalog was the go-to item for acting out your fifth-to-seventh-grade fantasies (and in some cases, probably beyond). :o

Is the OP possibly thinking of the movie The Great Outdoors?

I keep thinking of that scene where Dan Aykroyd’s character is in the bathroom grooming himself, and his creepy twin daughters are staring at him, and he asks his wife, “How come (John Candy’s character)'s kids look at him like he’s Zeus, and my kids look at me like I’m a rack of yard tools at Sears?”

One year I asked my dad how much he spent on us kids for Christmas. He flippantly said “$22”, and we spent all Nov and Dec adding and subtracting items from the Sears catalog to get just under $22. Talk about dog-eared pages!

By the way, we bought a small bungalow that had been a Sears house back in the day. But we had to pay more than catalog price.
