killer whales are fat because they have to stay nice and warm....

There is a difference between 'large' and 'fat'. Whales are the largest creatures on earth by a scale of many time above humans - the same criteria for fatness cannot be used to compare the two. Additionally, any fat a whale has is necessary to protect it from the cold of the oceans.
they are hunting whales right now for their blabber (fat).
They have a lot of body fat, so it might protect them from some of the cold.
Umm, the best I can do is say that I never really got those "___ so fat" jokes; I think they're stupid. I don't get this one either.
