Government documents aren’t always a source of amusement. They take months to crunch the numbers, weeks to churn out the report and days to run the gauntlet of editorial scrutiny. And even after they’ve been through the countless fact checks, rewrites and resubmissions, they end up so dry and informative that they you often find yourself using one as a pillow.

But now and then, if you’re lucky, you can find nuggets of pure amusement. I found these in the 2010 Canadian Border Services Agency Customs Specifications report. So here goes, 7 random things that you can bring into Canada duty-free:

1 Human Hair – Don’t laugh, maybe that’s why hair transplant clinics are booming.

2 Slag and industrial waste – unless you’re running a roadworks business, I wouldn’t worry about this too much.

3 Used rags – maybe it’s because ShamWow’s doing so well.

4 Military helicopters – just in case you wanted to start a coup or something.

5 Imported aircraft – I suppose they’re desperate to clear up foreign aircraft depots, but whose walking around with a million in cash these days?

6 Radioactive isotopes – hey, they closed down Chalk River didn’t they?
