I'm white and a runner (albeit treadmill, not outdoor) and found this funny. It's the running in the snow bit. I think the joke could have been handled more tactfully if it were framed in a general "Why torture yourself" way instead of pointing out the skin color.
Foxtrot did a comic like that and it was pretty funny.
Jason: "Why does Mom run, Dad?"
Dad: "To keep herself good-looking and healthy."
(Mom passes by, sweaty, wheezing, tired, frazzled hair, etc)
Jason: "No, really, why does Mom run?"
Your comic idea is funnier.
your cartoon was funnier...universally acceptable...
thanks for the insight - sometimes I chuckle at runners/bikers like sKerry whose clothes cost more than my car...
