Price check!

No condoms in there? Now I feel old.

If you're buying those three things, chances are good you don't need condoms.

Kieran said...

Ha ha ha, what about Hemorrhoid cream?

It makes me laugh out loud thinking about items at the drugstore that are both laxatives and wart removers. It does make me wonder though, do you really not understand how Venn Diagrams work? Or maybe all of these circles on the blog aren't actually supposed to be Venn Diagrams at all. Any way, I have go pick up some laxative acne cream. Catch you later. :)

Maybe she does know how Venn diagrams work and you're just misreading it. Add the word "buying" (or a verb of your choice).

birth control has to be the number 1 burner for a price check.

Mike Machenry said...

I'm not so sure, anonymous poster. Even if you add 'buying' to each word, you still wind up with the only people who don't make eye contact with a cashier being the people who are buying all three products. Maybe that's the intent.

One thing I find amusing is that wart remover and acne medicine are often exactly the same thing, salicylic acid, which has been replaced as an oral medication by its less caustic chemical brother, aspirin.

I went through the express aisle the other day with just a box of condoms and a box of Preparation H suppositories. I was tempted to tell the cashier (50+ year-old woman) that the two items had nothing to do with each other (which was actually true), but the opportunity never really came up. Oh well.

Ok, you finally managed to make me post: To me the "laxatives" circle contains the properties that all laxatives have in common. It's not the actual extension of "laxatives" but rather what you could call intension. IMHO most of Jessica's Venn diagrams are meant to be read this way. Don't you see it?

Mavy, I am trying to see it. I don't really yet. I just found the blog and I find most of the sentiments entertaining. It's just hard to follow the use of Venn Diagrams the way she does it. All the graphs seem to be used exactly how a graph is normally used. But there's one Venn Diagram in an old comment where one small intersection of two circles is "Everyone in the world" which is really just not the way Venn Diagrams work at all. It does seem like there's just no understanding of a Venn Diagram but I'm betting it's just artistic license. So I was hoping to get an explanation but I don't understand yours. What's extension and intension?

cas said...

perhaps "store brand" should be added to the diagram as well

Seth said...

I think some of you folks are trying to read this one a bit too literally!

mavy said...

The extension of a term is just the set of all "things" that the term describes. The extension of "prime number" is the set of all prime numbers: {2, 3, 5, 7, 11, 13, ...} . Given the extension you can decide, wether a number is prime or not: you "just" have to check, if it's in the extension or not.

But of course that's not the whole story, what are primes after all? Enter intension.

The intension of a term on the other hand is the set of all properties of the things the term describes. If you know the intension you know the meaning, it's something like a description. So you can build the extension yourself: you just have to check, if all properties from the description hold. The intension of "prime number" would be something like: "has exactly two distinct natural number divisors"

See also Wikipedia: Intensional definition

How does this relate to Venn Diagrams? Well, each point in the real plane could represent some property. Then by drawing circles you can combine several properties to build the intension of a term: the points inside the circle are properties that hold for your term, the points outside the circle are the properties that your term does not have. Terms that share some properties will have a non-empty intersection.

Argh, being meticulous again. +_+

add "tampons" and "vodka" in there, though, and you've got a party anybody can be proud of!

random stranger says to mike machenry, here's a wordy explanation of what went through my mind during the half a second between reading this index card and finding it amusing:

how embarrassing would a price check on this item be?

laxatives have these associative properties (eg, relieving constipation) when you bring them to the cashier
::low embarrassment; my tubes are just clogged

acne cream has these other associative properties (eg, skin care) but share these ones in common with laxatives (eg, could be used for pranking)
::medium embarrassment; I'm teaching my kid a lesson in body care, but this might look like a mean joke

wart remover has these other other associative properties (eg, wart removal) and shares these ones with both laxatives and acne creams (eg, weirdest fetish ever??)
::high embarrassment; I'M NOT A PERVERT JUST GIVE ME THE ITEMS AND DON'T ASK QUESTIONS! price check? floor, you may swallow me now.

"Can I get a price check on isle two for the 'Nude Grannys' pinup calendar and Johnson & Johnson's Hand Cream?"

Once while working in a drug store, I had to call for a price check on Monistat, twice. The customer nearly died of embarasment.
