I've always suspected my Collie, Mama, is smarter than I am. Some research folks in Europe have apparently heard of my insecurity, and decided to prove me right...

The New Scientist magazine reports a Border Collie named Chaser can identify 1,022 toys by name, easily surpassing the previous record of 200 held by another Border Collie, Rico. (Are all Collies this smart? Maybe I should ask Mama.)

Chaser's accomplishment wasn't easy, though. NS says it took over three years of intensive training for her to gain her smarts.

And maybe I don't need to worry too much, anyway. I doubt that I've even uttered 1,000 words in front of my dog. And who would she tell?
