That's What She Said

I might seem immature for saying this, but I'm almost 17 and I still think the "that's what she said" joke is so funny. I just cant get enough of it. I'd like to do them all the time. Sometimes it's the only thing that gets me through a class. A teacher say's "yeah I know this problem is a little hard" and I'm trying hard not to burst out laughing. (by the way, if you're a true fan of the "that's what she said" joke then you'll notice that the lines 2-4 are part of the joke).
