Seeing Happy Phantom's mention of Yahoo Answers...
reminded me of my trolling hour. Yes, a whole hour. The gist is that I was put in the direction of the site by a friend who said "it aint great, but it does sometimes get results."
So I posted a Q about PDC's (something to do with wheel ratio's or bolt distances etc) and whilst waiting thought I'd check out the jokes for a giggle. I then noticed one user on every single joke who posted 'HaHa. Funny.' to EVERY joke. Wow, methinks a troll is about. Not abusive or annoying, just answering every joke to get points. I thought this was sad but an opoortunity to troll her/him/it just for a challenge.
Task one was to try to get my post directly under theirs and leave joke/smart alec comment. this went ok, managed it twice.
Task two was to try to get there first and predict the inevietable response. Not bad, four successes!
Lastly, I decided to take direct action and post stupid/non-funny/no punchline jokes to see if I could get the response and be able to spit sarcasm at the troll from the edit button.

After ten sad jokes and lack of suitably sarcastic responses I gave up having wasted an hour and a half trying to catch out someone I don't even know, let alone if they even cared.

Trolling is a very boring and sad existence from my own limited experience. Got the answer to my question, though. So not totally wasted.

It's PCD not PDC-Pitch Circumference Diameter. (I would normally call you names such as twat or fucknugget but I have a rather large Sunday morning pooh brewing and it is going to be too good to miss!)
