I was hoping you guys could help me with some creative prosthetic ear solutions. Specifically, the ears in the pic.

Any time the temperature gets anywhere close to summer time, I sweat like a pedophile at Chuckie Cheese. This makes spirit gum too weak to hold my ears on. I could use liquid latex, but that will damage the ears and cause me to replace them after only 2-3 uses. And, to make matters worse, I'm going to be fighting with these things on. The rules state no head shots, but mistakes happen.

So, does anyone have a good idea for holding these ears in place that doesn't involve adhesives? If it helps, I will be wearing glasses as well, if anyone knows a way to attach the ears to the glasses without them falling off.
