I don't give a sh*t.

One time, on a beautiful sunny day, three good friends made a deal to not give a shit about anything anymore.
After some time of walking behind eachother, one guy notices a 100 dollar bill, stops above it, and thinks whether to pick it up or not.
Then he says quietly:
"Aaah, fuck it, i don't give a shit about that money".
And proceeds to walk.

Second guy saws him looking down and notices the dollar bill, and as he is approaching the money, he remembered about the deal they had just made, and then thought:
"Fuuuuck that, i don't need that shit".
And also proceeds to walk slowly forward, pushing down the urge to pick it up.

Third guy approaches the dollar bill, leans forward and picks it up. Other guys were immideately confused.
And one guy asked: "Why did you pick it up, we said earlier today that we don't give a shit about anything?"

Then the third guy says to them: "I don't give a shit about what I said".
