Overheard conversation between police officers...
Now then, listen up lad. This 'ere is yer 'eckler & Koch MP5 automatic machine pistol and that, in yer 'and, is yer standard six ounce take-away coffee cup. You see the basic difference between yer machine gun and yer coffee cup is that when I go up behind someone and shout "Stick yer 'ands up!" they jump a bleedin' mile; whereas if you tried it with that they'd just think you were a bit of a numpty, know what I mean?
Now then, don't get me wrong lad, I'm all for learnin' on the job so to speak, but I thought they would 'ave gone over this back at training college; know what I mean?
By the way, I may have made up some of this..... the coffee cup can actually be a lethal weapon in the right hands :)
