I shocked the electrician with thunderbolt and advice him to go home because of bad weather.

I leave a ball of cheese the size of a boulder on top of a hill and kick it rolling.

I donate the cheese boulder to the giant mice living near my castle. The mangled remains of the people it crushed to death while rolling down go to my lizards.

I leave a used condom to the next user.

I send in a squad of cleaners to disinfect the surroundings and seize the genetic material found on the condom.
The analysis of the material allowed us to create a rough sketch of the culprit.
I leave some wanted posters with that sketch, depicting an individual half man, half Komodo dragon.

I leave a 1-use-get-in-free card for a strip club that's both too far away for me to visit and probably too full of smoke to be worth visiting.

Since we are all wearing masks, the smoke doesn't bother me, so I grab that ticket. Cool, thanks.
I leave a bouquet of flowers that I wanted to give to my wife as an apology that I went to a strip club. But then I remembered, I'm not married at all.

I don't care for art, so I sell it on ebay.

I leave a nuclear bomb to the next user.

Not knowing what it is, I explore the knobs and switches until a countdown starts. With a hearty jog, I leave it to be addressed by the next person.

How rude, that bouquet of flowers would have looked beautiful next to the Syphilis-poster in your man-cave.

^ I call the guys that dealt with the condom, they know what to do.

v That didn't go as planned. I leave the phone number of one of the (female!) strippers, her name is supposedly Michelle.

v *leaves you a rent prophylactic*

I leave you with such things as have been accumulated by previous posters: A nuke on a countdown, a stripper called Michelle, and a prophylactic. I also leave the question: Now what?

I discard the question, it's not my problem when other users can't deal sensibly with their stuff and make a mess of things...I'm not responsible for their sex or drug addiction, or for their playing around with nuclear weapons.

Since I want them to become responsible adults, I leave Jordan Peterson's book "Clean up your room (and learn to disarm nukes you activated yourself, don't ask morolf to fix things for you)"

V **I leave you a trail of breadcrumbs out of this thread and to one less problematic and tedious.**

I notice the trail, but why would I want to leave a thread where I can get stuff for free?

I leave a samurai sword to the next user.

I use it to cut down my neighbor's bamboo forest and leave the bamboo for the next user as building materials.
