SPOILER: The joke was used in a social psychology experiment. How far you read is supposed to say something about your personality. I read the whole thing!

I read two sentences, then jumped to the end for the punchline... what does that say about me?

I read the whole thing, and enjoyed the process. Even recited a very shortened version to my hubby, who groaned. :)
I liked it.

Same.

I just jumped to the punchline without reading the first two sentences. I skipped all the psychology stuff, too, so I don't know what that says about me...

Not only did read the whole thing and love the entire deal, I plan on foisting it onto many of my friends and relatives in the oral tradition as soon as humanly possible.

s**t! That good! I better go read it.

I read the entire thing and the analysis.
/pats self on head

I read part of it, got bored and scrolled to the punchline, then read the analysis.

Luckily, I had nothing else to do. Listened to music while I read it. Thought, if it truly is a joke, it doesn't have to be THAT funny. So I read it all, like a story instead of like a joke. I found out that I'm in the first group - 11% - and that I like to take life as a journey. I'm patient and it confirmed that. Doesn't matter that it was a shaggy dog story. It's 42 meters tall!

I read the entire thing too. And when I was done, I was sad that it was over. I felt the same as when I finished the (extended) Lord of the Rings trilogy movies for the first time.
