Oh, I love wearing fun hats and the animal ear headbands, when I was in Marching Band a few years back I'd always wear one of my sets at the competitions and football games, and sometimes just during practice. It's fun sure you may get some odd looks, but most people find it amusing.
In Disney I usually wear the headband ones so my head doesn't sweat too much.
And you know what, i really like that idea of being buried in your mouse ear, err, well I wanna be cremated so maybe that's a little morbid to be thinking of, but it's a good idea none the less
