A GOP and a Dem were on an ice berg and sees a polar bear swimming toward them...
Dem: You see this... of course it has to swim. Last year, at the exact same time, this was not ice berg, this place was solid ice. And the polar bear could have ran instead of swimming. Now, do you take 'climate change' seriously... now, do you believe in global warming?
GOP: I don't know what you're talking about... but this is the reason I bring my gun everywhere...
pop, pop, pop... Polar bear dead.
