Slag (22 Dec 10 - 05:37 PM), "Me and you and a dog named Boo" has that "me" for subject as mentioned by other posters above, it should be "I" (in noncolloquial contexts). Secondly, by conventional modesty, "I" should come after "you". Also, "a dog" would be wrong stylistically, because the fellow traveler being addressed will know the dog already.

"You and I and that dog named Sly" might be better. But then, lyrics for feel-good songs are often "incorrect" on purpose, to symbolize freedom from pedants like us [objects!]. We just gotta know in case we write texts for more formal purposes.
