I KNOW, the only thing close to jingles are these lame things that don’t even rhyme. Like, “Mattress Firm, it’s a gray place, to get a good night’s sleep.” (Or maybe it’s “good place to get a gray night’s sleep.”) At any rate–doesn’t rhyme, sounds lame, and the woman singing it has serious enunciation problems.
I fondly remember things like “Hold the pickles hold the lettuce/special orders don’t upset us” --bonus points for an internal rhyme.
There are a few still on local radio. Here’s one of the ads played on my town’s radio station:
Frankly, if I needed glass or mirror replacement, I’d probably call them, since I can actually remember the business name and phone number. 
Local chimney sweeping company (which is retro in and of itself) A Step In Time totally does the jingle thing to the hilt still. http://www.youtube.com/watch?v=uDCFlorPI_o&feature=related
ETA: Even if I can’t remember the whole thing, I never forget “dial C-H-I-M-N-E-Y!”
Home-home-home-home of the one dollar install!
See how far your mind can take you… at Apollo Coooollege!
I hear jingles all the time. Then again, I’m a product of the '90s so maybe I just haven’t experienced what you guys consider true jingles.
The Honeycomb jingle was lifted from a popular song of the same name. Jimmie Rogers recorded it in 1957.
A true jingle is more than 10 words.
Another fave from my teenage years – the Bekins jingle. (Taken from here.) I saw a Bekins truck the other day and reflexively started singing it.
Bekins men are careful, quick, and kind
Bekins takes a load off of your mind
Moving heavy stuff or a fragile fixture
A Bekins man is a moving picture
We’re the best-trained moving men around
In the moving business Bekins men are pros
And pros means poetry
In moving
Forgot to mention the HVAC company in this area that has a jingle that they tweak for heating and air conditioning seasons.
I was amused to see that they flipped into heating mode last week even though today’s forecast high is 92 degrees.
Late last night I woke up shivering in my bed.
That danged old furnace, it was completely dead.
So I called Morris-Jenkins and they very kindly said
You’ll have warm heat in your house tonight!
The summertime version is
Late last night I woke up sweatin’ in my bed.
That old air conditioner, it was completely dead.
So I called Morris-Jenkins and they very kindly said
You’ll have cool air in your house tonight!
Catchy, not excessively annoying, but memorable as hell.
Here’s one from Washington State:
But speaking of Buster Brown-“Pluck your magic twanger, Froggy!”
There is a place here in Kansas City with a jingle that is pretty effective and quite short:
Less of you, more of life, Weight Loss Surgical Center!
