Hard to choose, they are all great in their own way.
I guess "The Deadly Mantis" because of the "little man in the boat" joke that has changed meaning in adulthood from when I saw it as a child. Eegah and Manos do stand as cornerstones, but Mantis has that one line that is burned into my association with the show and holds a special memory.
Definitely an axe stone, I have one like it for keeping my American woods axe keen for limb lopping and light felling.
You could use it to sharpen a pocket knife, but they are usually too rough to get a fine edge. Fine for a knife that does rough work like a woods knife, but a pocket knife should be sharper than the stone can do.
It isn't outrageous that you have them, the problem is you keep them in an illuminated bookcase in your living room and keep wanting to feature them as part of the tour.
You can shoot an AR-15 pattern rifle, including the military versions, with the stock up against your nuts and it won't hurt. The recoil is very low because the power is very low and the system of operation absorbs a lot of the energy, combined with the weight of the rifle means it is soft shooting. The stock doesn't need to touch your shoulder for you to be accurate with effect out to 50 yards or more so long as you do your part.
Honestly, just having it pulled against any part of your body with a decent view of the sight is enough to ring steel or put holes in paper.
Granted, the water is frozen solid with no means of warming.
I'm not into muppets.
Porn has a plot still; a member of your family that you may or may not be related to by blood is either stuck in an appliance or furniture, is pretending to be your significant other, is going to teach you how to perform various sexual acts, or you fuck the service worker.
We don't have the same attention span, so we can't have the complex and well written telenovela erotica that was featured in the back room of a movie rental place you visited when your wife was going out of town for the weekend and the kids were at camp.
The next generation's porn will be 7 seconds long, all cumshot close ups. They will call it "swipe stroking" and there will be challenges to last 10 swipes.
You're talking autoerotic asphyxiation, the article is talking about one person choking another.
In current mainstream thought gender =/= sex.
So your second point should be phrased "Is changing sex also (soon to be) possible", as sex is genetic and gender is a concept.
Maybe with some radical gene therapy sex could be changed, but I imagine that to be a rather long and unpleasant process if physical changes happened. It would probably be more feasible to make a clone with the different sex and then transplant consciousness. That just raises further questions like if you died and is that still you. Probably before that is viable we will be uploaded to computer systems to escape the environmental effects of our actions and your avatar will be up to your whims.
What it is like to chew 5 gum, on DMT.
Or go to Mexico, got to TJ for a root canal for a third the price and get $75 hookers that you pick from the strippers in the club below the hour rate hotel. You can get a root canal, 4 hookers, a hotel for a few days, and a round trip ticket for the prices of one root canal in the US.
In America, you "have to" due to government regulation(IRS wants their cut of the tendies).
