Ice Cream
 

You scream, yada yada yada... Just what America needs, 10,000 calories for 35 cents.
Of course it's a joke, a gross exaggeration, but it's strange to think at that time it was an acceptable advertising gimmick.
Today that would attract outrage from picketing nutritionists.

Let's see. Most calories per gram? Fat @ 9/gm
10,000cal/9cal/gm=1111.11gm
1111.11gms/28.35gm/oz=39.2oz pure fat/10,000 cal

heavy cream (94%cal from fat) = 1 cup fluid = 821cal x 12 cups =10000cal

Let's suppose that some sick bastard thinks an ice cream sundae made of lard is a real thing. You'd need a bit more than a two pound lard sundae to = 10000cal

Let's suppose some slightly less sick bastard thinks that heavy whipping cream alone would make a better sundae. You'd need 12 cups or 3/4 gallon of whipping cream to = 10000 cal

Let's say you were not insane and you made some really rich, premium ice cream, that would average about 66cal/oz. You'd need 151 ounces of ice cream or eleven pints to hit 10,000 cal.

Even cool hand Luke couldn't eat that much lard, cream, or ice cream.

Ice cream...

You scream...

The cops come...

It just gets awkward...

Maybe they are referring to scientifically defined calories instead of food industry calories? There is a thousand fold difference between the two.

Awesome reference.

I thought about that when I considered typing Kcal instead of 1000 calories. But if there are 10,000 small calories, then the sundae would only be 10 food calories, or about a teaspoon. Micro Sundae.

I think it's more a sign of the times. 10,000 calories was a positively ridiculous number back then--might as well have called it a million-calorie dessert. Nowadays, we're like, "Well, it's excessive, but certainly not impossible. Heck, that's less than 6 Chipotle burritos..."

Ahh, the Highest Number
