I call Evan Mongoose because at the Olympics we had a joke of always talking in Midwestern, Minnesota, Illinois accents and Mongoose sounds funny if you say it like that. Mongoose is also just a completely different animal than a swan, like Evan and I and it was a cute, funny nickname. Evan didn't know what a mongoose was, so I had to tell them it's a rodent that eats snakes like Riki Tiki Tavi and I think he got it. In any event, I have a strange sense of humor and I love that nickname.

Blogger's note: Johnny said at the beginning of his explanation: "Evan has called me Swan since the Olympics for obvious reasons; sometimes he even says, 'Little Swan' in a Russian accent, but in general, Swan."
