I think the only place you'd find a polar bear and a lion in the same vicinity would be at a zoo. The polar bear would be playing around in his simulated arctic environment looking at the lion, like "Chill Bro, have a frosty cone". And the lion would be like, "Goddam it looks cold in there". And then go off to find a nice T-bone that the zoo attendants left out for the tiger.
