You take a small plastic frog, put in on your cat's back,and have it 'hop' around while you repeatedly say ribbitt...you might be an Aspie.
If you're culling some fruit at work and it suddenly dawns on you that plums would be the exact perfect size to be put in a trebuchet and fired at people, and wouldn't THAT be cool...you might be an Aspie. (Plums are also the right size for a quick game of catch.)
If you refer to anyone and everyone as 'dude' because-well just because...you might be an Aspie.
Feel free to add to my list.
Btw:I'm calling Autism Speaks on Tuesday-Because they can help me 'hang' them. I want my post on A.S. to be blunt but factual.
