And you don't get sore ears[1] from the pressure like you do with a buff after a couple of hours.
[1] Your ears may vary in rigidity and sticky-outyness.
I thought that was just me!
I had an ex with an adorable little brother (in as much as any 10 year old boy can be adorable, naturally) who had - well, presumably still has - comedy sticky-out but bendy ears. His party trick was to fold them up and tuck them in, then cause them to pop out at will. My shock at this naturally lead to a discussion of the rigidity of ears, asking everyone we met how bendy their ears were, etc, and he declared mine to be freakish and stiff.
Still, at least they're symmetrical enough to hang a pair of glasses from. That would be *really* annoying.
