Don't work for my old man...
My father, being a self-employed builder, generally spends most days just trying to avoid killing himself in ingenious ways - or in this case someone else.
One day, the old man is removing the mortar from a brick wall with his weapon of choice - the angle-grinder (All safety features removed, obviously). As he gets to the corner of the wall, he's unable to reach into the corner with the 9 inch disc, so thinks "Fuck-this" and slaps the 12 inch bad-boy on it. Now it's worth reminding ourselves that the angle-grinder revolves at several hundred rpm.
While all this is going on, he's got a young labourer behind him cutting bricks in half. All of a sudden, the old man hits a snag in the wall and the massive torque rips the angle-grinder out of his hands and flying behind him. Cue father, turning round to see his young employee doubled up in agony on the floor.
"Oh shit" he thinks to himself and rushes to help the young fellow, who as it turns out was very, very, very lucky indeed. Fortunately it was the middle of winter and the seventeen layers of clothing he was wearing had stopped the blade enough to just nick his skin. If it was summer, the old man would have turned round to see the poor fella sliced in half, or at least with his guts hanging out.

Being a kind and generous employer, he gave him the afternoon off work.
