That really dumb idea...that you are secretly afraid would sell like hotcakes

Like a solid plastic cube 5.6 cm by 5.6 cm, with each side painted with one of six different colors-Rubik’s Paperweight.

Yours?

Cocktail packets, like powdered alcohol encapsulated inside flavor dust. Pop one into your morning OJ to make a working man’s mimosa, say. It’ll never taste very good, but if it works for ramen, why not booze…?

Deep-fried sushi at state and county fairs.

Not a dumb idea, I’m afraid: Alcohol powder - Wikipedia

Beer bottles that have caps with puzzles you have to solve in order to open them. If you can’t, it means you’re too drunk and need to stop drinking anyway.

Isn’t that already a thing at most sushi restaurants in the US? I’m down for it also being fair food, but it doesn’t have the novelty factor of deep fried yak tonsils.

A drive-thru coffee shop that sells slices of cold pizza. The perfect breakfast to eat on the go. Contract with existing pizza shops for leftover pizza at a discount. Serve cold the next day.

Placebos, advertised as such.

Remember the International Star Registry ?

I suggest the International Stop Sign Registry!

For a mere $35, we’ll name a stop sign somewhere in the world after the person of your choice. You’ll get a photograph of a real working stop sign, and a 10 page booklet explaining the workings and history of stop signs thru the ages.

I think it’s a billion seller…

Men’s trousers in odd-numbered lengths.

Marks and Spencer (in the UK) sells their own brand of trousers in lengths of odd numbers of inches. They don’t seem to make any in even-numbered lengths.

You can get one for your loved ones. “Stop! In the name of Love!”

I’m old enough to remember when they were available in stores. I’m a 31 length and as a result have to take ‘em up or look like I’m a crewmember of OG Star Trek.

Sorry. Homeopathy beat you to that and has patented their approach.

Ornate pocket-sized hammers that teens would buy to hit themselves in the head. The idea is that it would drive their parents nuts.

I’ve had the same idea. I don’t think it’s a dumb idea at all, I think it’s brilliant!

Add a warm pop option and it’d be a nostalgic reminder of past slumber parties.

Rarely drive-thru, but otherwise already a thing in Germany. Many German bakeries sell cold pizza and/or other pizza-styled and flavored baked goods around the clock.

I too have had this idea for years but I would throw cold fried chicken into the mix.

Cold foods made the day before, vacuum sealed and refrigerated (but not frozen) for consumption the next morning.
