As I started eating the pieces of taro I'd stir fried, I got this tingling feeling in my mouth. The tingling turned into a sharp pain that made it hard to swallow. Was this taro or had I made a mistake?

I rushed to the local public library and got the librarian to log me onto the internet so I could look up "oral/throat pain upon ingestion" in the online medical sympton dictionary. "Go to google, please", I told her.
She got me to http://goggle.com and asked if this was what I was looking for. The librarian had never heard of Google before. Son of a bitch. That explains why Hawaiian kids are so dumb.

I took over the console and started doing searches in a database of poisonous plants. As it turns out, all taro are naturally poisonous and are spiked with an irritant called Calcium Oxalate. I hadn't cooked the root long enough to denature the toxin. Damn. That was a pretty stupid move.
