One should point out that in Van Halen songs and other songs of that era there were often spoken word parts of the song that help establish a greater story that was occurring within the song. In the Motley Crue song 'Girls, Girls, Girls' we as listeners are literally riding along with the band on motorcycles as they decide on what to do that night (go to the strip club). In the Van Halen Song 'Hot for Teacher' we are one of the students in the class room.
Hey, I heard you missed us
We're back! (Hey!)
I brought my pencil
Give me something to write on, man!
We're back! (Hey!)
I brought my pencil
Give me something to write on, man!
Classy. Still, I like the song.
