Americans vs. Brits

My entire class is taking on my British prof tonight. The question...
"Don't Americans work more?"
my prof - "Americans spend more time at work, yes."
"Well Americans are more productive than British people too"
my prof - "What was that? Once you take out the housing market, you're not actually as productive...hahahah Brits live longer too - there's a reason..."

We also argued whether you call a phonebooth a phonebooth or a tellyphone box. One of my friends said, "You know, the thing Superman changes clothes in."

There are others, but class is letting out! hizzah!
