Who's the nerd now?

Learned a fun little fact while browsing on dictionary.com... (I love words!)

Did you know Dr. Seuss invented the word nerd? 
The slang term, which means "and intelligent byt single-minded person, obsessed with a certain hobby or pursuit"first appeared in Dr. Seuss's 1950 children's book If I Ran the Zoo. 

According to Seuss, a "nerd" is a small animal from the land of KaTroo, not the pale kid with taped glasses that we think of today!

And no, I'm so not a nerd for hanging out on dictionary.com.
