Vigorish: Touche Dilbert!

I thought I was the only cartoonist who tried to educate his audience with GRE vocabulary lessons in my strips, but lo! Today's Dilbert impressed me with its rather improbable use of the word vigorish - a word I had to look up (something I haven't had to do since I stopped getting Zippy the Pinhead in my local paper). Bravo Scott Adams, bravo.
