I ate a serves 4 lasagna all by myself once. I routinely eat 1 and a bit pizzas (mind you, Australian pizzas are slightly smaller than American ones). I used to brag about my eating ability a lot because I am a stick and eat like a sumo but after being in the US I realise that your "serves" are smurfing ridiculous anyway. No wonder most of your population is fat (Australians have no excuse).
