Because your pissed about your lisp

The story:

I never really gave this song much thought (as I am not much of a Hall & Oates fan), however, as I was at work one day, I was sitting in the break room (and yes, I was on break!) listening to the piped in music through the ratty speaker in the room, and I couldn't quite figure out what he was singing, and this was my best guess. I asked a co-worker about it (knowing they liked Hall & Oates) as to what the real lyrics are. Having been told, I burst into laughter at myself, and only got a cold stare when I told them why I was laughing.
