Well, I guess it could be.
I was thinkin' more like a used car salesman though.
I understand what you're saying.
But back when, we used to use the term when indicating some staged event, elaborate formal procedure, ceremony, etc that was meant to copy "the real deal", but which was a pretty poor imitation ... but thought good enough by those staging it to impress the dumb local yokels.
i.e. The old dog and pony shows that'd put on their shows in little towns too small for a real circus to visit. Real low rent, low budget events trying hard to imitate a real circus ... going through all the motions to at least pretend they were just like the real thing.
For what its worth, I can remember that as a youth I attended a couple such. They billed themselves as a "circus", but grandpa called em dog and pony shows. However, we still went. Fact was, wasn't likely we'd see anything better locally. Back in that time and place, there wasn't much for local entertainment, so it didn't take much to draw a local crowd.
Chuckle, it came to my attention, even at my youthful age at the time, that the basic formula for such a dog and pony show to attract the adult men ... so that they'd bring their families ... was pretty simple. Have lots of beer to sell at a reasonable price ... and have a few reasonably pretty ladies on staff dressed in not so much. Not so much, for the time. Dresses that ended above the knees, or exotic gypsy skirts slit up the sides, or a costume equivalent to the standard (conservative) one piece swimsuit of today. In that time and place, adult men RARELY ever had a chance to see much skin on a female they weren't married to. They'd drag the family to the dog and pony show ... just for that.
Anyway, I've always thought of a used car salesman more as a flimflam man or snake oil salesman.
Terms I still use to this day. Have had to explain them to my kids and grand kids, tho.
Mines a slang word I came up with as a kid - Gription. It's like traction, but only with your hands. Anytime I'm working with something slippery and can't get a good grip I'll say I can't get any gription on it.
Where I work we've been using gription for several years. Also have another one- toolage. "I'm gonna get some toolage and go on the roof and check that blue oval box again"
Nemo me impune lacessit.
How much blood do I have to bathe in to get clean?
Don't look down on anyone unless you're helping them up.
Panther piss - WD40
Rue Goldberg fix - half-arse repair
light a shuck - leave (think I saw it mentioned)
Thermostat removal tool - HAMMER
50-50 AC - roll windows down half way and drive 50mph
plug nickel - not worth anything
Hungy enought to eat the south end of a north bound cow
So hungry my stomach thinks my throat's been slit
Sorry, could think of single word, just phrases..
"Fortunately, I keep my feathers numbered for just such an emergency." Foghorn Leghorn
Spend a dollar to save ten cents - pointless repairs or work that will only cost more than it's worth
That don't pass the sniff test - Something about the situation just doesn't feel right.
(The wise men of modern thought) adore a god made of putty or of wax - plastic, effeminate, molluscous, with no masculine faculty about him, and no quality that entitles him to the respect of just and honest men, for a being who cannot be angry at wrongdoing is destitute of one of the essential virtues, and a moral Ruler who is not angry with the wicked, and who refuses to punish crime, is not divine. ---Spurgeon
