I'm not really sure, but you might want to take a look here (
http://www.dafont.com/) to see if you can find it or something close.
Also, as a suggestion, when asking for assistance, it's helpful if you can provide as much information as possible. You don't have to write a book, but screenshots, links to webpages, etc. can facilitate a faster and more specific response. For this particular question, I had to figure out what/where "crash course" was and then try to figure out which font you were referring to. I know there was only one font in the sig, but when I went looking, I didn't know that.
I'm glad to provide assistance, but if you can "help me, help you" it really improves the communication.
