My Brother, The Easter Bunny?

Okay, my brother has been walking around my house wearing a pair of bunny ears for the past week. They were mine but I decided to give them to him on account of not wanting to wear my brother's nasty scalp sweat. Originally, I had bought the bunny ears for an autism charity but to my brother that translated to "Oh my god, you brought bunny ears for my head. Thanks!"

The really sad part? He's 13.

Help...Me.
