(You) got to have faith!

Ersatz
- Being an imitation or a substitute, usually an inferior one; artificial.

Yegg
- A thief, especially a burglar or safecracker.

QED
- quod erat demonstrandum (which was to be demonstrated).

I went to look up the first word because my quantum booked used it and I sort of understood what it meant, but I wanted the right definition. Then I looked up QED because we also use that a lot in Quantum. Then I spent the next half hour flipping around the dictrionary looking at random words. It is very interesting. I wish I could remember all the neat ones I read. Oh well. I at least remember Ersatz. I wonder how I can use that in a sentence...
