It's all a question of perspectives, GHoST.

The joint is over there, relative to your postition, so the task is to get the joint over here. The joint has no automotive power (ie, it can't move by itself), and yet you cannot remember how it got there. So, you must have put it there. All you have to do is remember to get it when you next have to move (ie, go to the toilet, or summat), then you won't 'actually' be getting the joint, but rather you'll combine it with another action. That way, the joint will be over here, without you having to actually bring it over here as a defined task.

Do you see?

Can you tell me what I mean?

Economy of movement, dude - it's the "Way of The Stoner" lol

Oh, and "dielemma", init?
