You think Ukraine is game?

At work recently, two of my coworkers, who happen to both be Ukranian, walk in from outside dressed in full winter gear. Another coworker stated, "You're from Ukraine! Isn't it much colder there than here?"

(I may be paraphrasing a bit here.)

Reply: "Well we wear coats there too!"

Coworker: "I've seen people in Canada wear shorts and T-shirts in colder weather."

Me: "Are you saying that Canadians are stronger than Ukranians?"
