My grandparents owned a small farm which was the "family headquarters." My grandmother always had to be ready to feed a crowd, so she'd keep a big roast or two (or other meat) wrapped in butcher paper in her big freezer. My aunt's fiancé (now husband of many years) was working on his graduate degree in herpetology (study of snakes), and the farm was a great place to collect specimens for his dissertation. He found a huge one down under the rowboat by the pond, and wrapped it up and stored it (yes) in grandma's freezer.
She set the package of meat out to thaw and then unwrapped it to roast with the potatoes carrots and onions. It's been 40 years gone by but i can still remember her scream when she opened that butcher paper and found a black rat snake several feet long!
