Maybe I was that guy, now that I think about it. I used to talk obsessively about my parakeets or my hedgehogs or my turtle. One of my friends (who was diagnosed with ADHD, but who I think actually had Asperger's) used to routinely push me off of a jungle gym and say he was sending me to "Birdy-Birdy Land" whenever I talked about my parakeets.

Granted, I was about 9 or 10 at the time.
