I don't know many people that still call it "Microsoft Office"... They usually refer to the individual apps they use (Word, Excel) rather than the suite as a whole.
Some people just call it "Microsoft" ("please install Microsoft on my computer"), especially if they're on MacOS where it's the only Microsoft software they use.
Some people assume it's part of Windows since they've only ever used computers that have had it preinstalled.
Unfortunately they no longer include elaborate Easter eggs like that, since they adopted a security policy around 20 years ago that forbids them. https://learn.microsoft.com/en-us/archive/blogs/larryosterman/why-no-easter-eggs
