Yes, it's possible to get carried away with this: An "are you sure" prompt that 
requires typing "yes"; or even more deliciously irritating, only accepts as 
positive:

"primateconfirmspreviousfilesystemdestructionwontsubsequentlyaskaboutdatarecovery"

Way, way more people will copy/paste that from a list or man entry, than 
acquire muscle memory for -f.
