HOLY snake.
No, you don't really have to shower, it's just a myth the upperclassmen tell you, I remember that one.
Though there are showers.... so I mean, if you want...
Or you could do what my uncle did and have a snake sliding contest. They got all lubed up from shower foam, and slid on their snakees at high speeds to the end of the shower. When he first told me, I simple shouted: "WTF" but the idea caught on.
No, no it didn't. This is coming from the man who told me I had a yeast infection when I thought my skin smelled like baking bread in the hot sun. 9 years later, I finally got it.
