By God it was funny.
Our house-master, a monk, showed it to us (I'm assuming you're referencing the documentary about the Scottish Tourette's sufferer called 'Jon's Not Mad'), presumably to invoke some sort of catholic compassion for the poor lad's plight. Obviously we all laughed 'til our sides ached.

For some reason the bit that made me laugh the most was when Jon was in a green-house with a bunch of other kids and a social-worker was gently helping him pot a plant, when he suddenly roars, "Your Mum's a CUNT!" The shock on the soppy social-worker's face before he regains his composure is comedy gold.

I seem to remember a scene where the family where sitting, rather glumly, around the dinner table with upturned Tupperware boxes covering the serving dishes.

Yes!
He phlegmed for England at meal times. His poor siblings did indeed look very glum. I think they'd rather ingeniously used perspex sheet-music stands to catch the gunk. Rank, it's putting me off my cornflakes even now...
