One of my neighbors has a fat gray tabby kitty that loves to bask in their driveway. I often pass the cat when I am running.
I suspect that it is old and likely hard of hearing, because I usually say "Hey, kitty!" as I pass, but it never reacts. Then again, perhaps the cat simply believes I am beneath him (one of the 99%).
Anyway, the neighbor's cat has a moustache. It's not as striking as that of this kitty...
...but its moustache is definitely there (image credit here).
Which brings me to the generational comment in the title. I had almost forgotten a similarly moustached cat from when daughter worked in a vet's office. We picked her up one evening after she was cleaning out cages, etc. and she was excited to show us "Groucho."
Except that she botched the name and called him--phonetically speaking--"Goo-cho." She was obviously too young to have seen Groucho Marx perform on TV or in movies, and in her cultural travels had also missed him as a show business icon. So Marx's famous moustache was simply not in her realm of experience.
