I have never ever had TV dinners even in my refrigerator. What kind of scavenging vulture do you think I am? But there are plenty of other analogous putrid options in Supermarket freezer aisles, not to mention what fast food joints serve up. My wife does do a fair amount of her own freezing. But my big film freezer is off limits. Last time she got in there and hid a frozen turkey in the bottom, she completely forgot about it until I exhumed it about 15 years later (inedible).
Up in your far north, native inhabitants have been known to eat Mammoth and Mastodon meat frozen for who knows how many thousand or tens of thousands of years, sometime with catastrophic botulism consequences. Way back then the early hunters would take 200 lb chunks of elephant meat and impale it on deeply sunk sharpened tree poles in "pingos" - supercooled tundra pools - the earliest known version of "flash freezing". Modern experiments with African elephant meat cold-preserved in the same manner and then eaten a couple years later proved completely successful. Of course, if you want to set up a wooly mammoth fast food franchise, I recommend removing all the wooly hair before deep frying it!
