Grandpa's in the Tuff Shed (1998)

It adroitly tells the story of a "counter culture" young man who when his grandfather dies, packs the body in dry ice, and stores him in a Tuff Shed, waiting for the time when advances in modern medicine can bring him back to life. I am not making this up. Then our young men gets deported back to Norway on unrelated charges. Then, quite a while later, people look up and take notice ... "Hey ... there appears to be a frozen dead guy in that shed over there."

Unfortunately the movie Grandpa's in the Tuff Shed is not yet available on HBO Max.
