Getting there. 

Ah, so you're the one who stabbed my pack of cornflakes in the back.... and with a score of 109% you're probably the one who slashed open my packet of toasted muesli and drowned the contents in sour milk.

Hehe, Alien Nation!  I remember that, think it aired in the late 70's and early 80's.  I didn't think much of it when it first aired, but my sister is into sci-fi as well and she hired the box set for a weekend a couple of years back.  We had an Alien Nation Marathon and I thought it was better the second time around.

Another way you can tell you ARE a psychopath... you watch sci-fi and think the villain is the hero.  I always thought the second Star Trek movie should have ended differently... with Khan blowing the Enterprise out of the sky and wreaking havoc throughout the galaxy, until Captain Janeway used her superior brain and stuffed him inside a whale to defeat him.

You might be a psychopath if you put a handful of scorpions in a disliked neighbour's mailbox and blow a whistle

[as is done in many areas when mail is delivered].

personally, I only do those tricks to those I do not like (the rest of the world)

harpo

LOL starkers!!

You might be a psychopath if you want a circular pond in your backyard and tie a donkey to a pole with a carrot dangling [from a collar its wearing] in front of  it to save yourself all the digging.

You would be a psychopath if you went to a public pool and threw in a Cadbury Picnic bar just to see how quickly it emptied.

You might also be a psychopath if you knew of a man who always got behind his wife's car to guide her while backing out of the driveway, and you plug her exhaust with doggy doo-doo so it becomes a projectile when she starts the engine.

Hehe, let's just say I was a devious SOB as a kid.

You might be a psychopath if you place a stink bomb in the central processor of your office block's air-conditioning... and the entire building has to be evacuated until the stink has dispersed.

You also might be a psychopath if you discreetly connect a 12 volt battery and generator to a [stainless steel] urinal.

Nah, would I do a thing like that?

You might be a psychopath if you put a joke dog turd [complete with artificial fly] on a sack of potatoes stored in the nextdoor neighbour's porch, then pick it up in front of her when she is horrified to see it... then a couple of days later you put a real dog turn in its place [using cardboard and perspex] and ring the doorbell before hiding behind a hedge.  Hehe, she comes out, sees the dog turd and says: "You're not going to fool me again you little buggers." before picking up the real dog turd, discovering her mistake and screaming blue murder.

Hehe, I did do a thing like that.

You might be a psychopath if you laff at others who are the butt of cruel pranks.

You might be a psychopath if you strategically place a mannequin [dressed in jeans & sneakers to conceal the artificial skin] under a car in a shopping mall parking lot, leaving its legs protruding slightly from the rear, as if it had been run over.  You then wait for the shopper to come put their goods in the boot [trunk] to see the shock, horror on their face.

No, you might be a pervert if you stand to ogle a model or a mannequin in underwear.

However, you might be a psychopath if you put a very realistic looking rubber snake on the drivers seat of the car of the bloke who took your place after your girlfriend dumped you.

Spoken like a true psychopath.  I'm proud, though you somewhat ruined my next post.

You might be more of a psychopath if you remove the rubber snake in front of him... but for next time you replace it with a bona-fide, genuine death adder complete with dual fangs and a full tank of venom.

Who knows, she may even get bitten on the face.... if she still does 'that thing' with her mouth during those short trip to the shops.  Two birds with one stone, so to speak.

Hmm, that's rude, isn't it!
