Cable TV
For everyone 50 and under, cable TV is a thing of the past. Most Boomers will probably take their cable TV packages to the grave at this point. It makes sense since it was something that they lived with for decades, but it's still funny to see how they haven't adapted to the streaming services that have such a grip on our society nowadays.
The Fuzzy Toilets
Fuzzy toilet seat covers had their moment in the 70s. Nowadays, they're just plain weird. Yes, they can be washed and yes they may be comfy, but they still just feel weird. A lot of Boomers may still have them in their bathrooms. Some people just like the look of a fuzzy toilet seat cover, I guess.
