I've sold sporting goods to HG Nelson (yes, really).
Several B-grade sporting celebrities went to my school: Jake Spooner, Troy Sachs, Shannon Taylor, Sandy someone (she won a world championship, but I'm too lazy to google her surname).
And Bruce Samazan who was a B-grade actor (although he was plain old Bruce Morrison when he was at school).
Without fail, they were unrepentant arseholes. Indeed, years after he'd left school, one of them
allegedly used to beat up his shcool-age girlfriend when they were living in a caravan park...
The other famous people I've met (Firko, TM Bill and Uncle Lozza) are good blokes, though.
