Blonde: “what does IDK stands for? ”
Brunette: “I Don’t know.”
Blonde: “OMG nobody does.”

My Thoughts: 

In realistic, IDK stands for “I Don’t Know.” Sometimes when people ask questions, and you are texting you can just reply back with IDK. It is shorter and faster and often makes sense as it is just a text. Obviously if you are writing an essay, you wouldn’t write it like that. Or if you are writing a document or anything you are writing you wouldn’t write it like that. IDK is made for texting and for conversations that don’t matter on the spelling error.

Joke 

To some people this joke would be funny, but for me it is just whatever. It’s like a middle school or high school joke that would be funny during those times. As an adult, it’s kind of lame and childish to me. Something that I would hear during young days in school.

False 

Also, this is just a joke, and I really don’t think any blonde would respond like that. Most of the time it is something that is common, and no brain required to even guess what IDK would mean.

Blonde 

I’m not sure why people think blondes are stupid, but probably when they color their hair, they clear their mind. Possibly, the colors used is enough that makes their brain cells die. I’m not sure where these blonde jokes started to rise from, but all of them are kind of stupid once you get older.

I used to hear this type of jokes in high school, and we would all have fake laughs. But after reading it couple decades later, it doesn’t make sense why we were even laughing for. Completely waste of time to say blonde jokes and more clever jokes instead of blonde jokes would make more sense.
