1. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

2. A stick of butter 113 g

   US butter sticks come in two shapes: the stubby 'Western' stick exists because West Coast dairies bought different molds.

   The Economist uses Big Mac prices to compare currency values worldwide — the famously tongue-in-cheek 'Big Mac Index'.
