Today I had

a serious conversation on a certain area of robotics with a European colleague. At one point he, in all seriousness, in a thick accent, used the phrase "mass distribution of the mechanical trousers". I so nearly lost it.

The Wallace and Grommit images, and the general inexplicable hilarity of the word "trousers", and somehow "mass distribution" becomes funny by association.... I was grinning, jamming my tounge in my cheeck so hard it developed a cramp. For the rest of the conversation, the phrase kept forcing its way back into my mind, and I kept trying to hold down bouts of uncontrollable laughter, little grins escaping from my control here and there. I think he must have thought I was deranged.
