From Chris Waigl on the 10th, this bulletin from Alaska, the 2/24 Nuggets cartoon by Jamie Smith (inksnow.blogspot.com) in her local paper, the Fairbanks Daily News-Miner:
[Chris:] [Since the cartoon is set in Alaska] the animals depicted presumably are caribou (NOT reindeer). Note that in caribou, females have antlers, often quite elaborate ones.
Also [since it’s illegal to kill caribou cows, but legal to hunt bulls,] the Alaska Department of Fish and Game has a remarkable multi-page illustrated leaflet about sexing caribou in the wild [here]
Ok: the idiom grow a pair; antlers on female caribou/reindeer; the distinction between caribou and reindeer; and as a bonus, an Ink & Snow blog posting “Bear Den” from 3/10 on the use of trademarked characters in cartoons.
