Hey Boo,
He's talking about the "Great White North", where bikini's are fur lined and anytime the ice is out, it's time to go swimming eh?
However, following Bergmann's rule, the further North you go, the larger the members of a species tend to be. Thus the bikini clad (or even nekked) 'babes' might more closely resemble a manatee to your eyes.... You know, "Warmth in the winter, shade in the summer"....
Jus' sayin',
