Funny that adverts are mentioned, as here in the UK I associate it with adverts of Vitalite margarine, which used a glorious parody of it - "wake up in the morning, wantin' some breakfast, tell me what am I gonna spread on my toast, oo-ooh, Vitalite".

I figured the song was about trying to make your way in a tough world without losing your morals and core values, which is still how it reads to me. Nunaya's comment about Bonnie & Clyde fits with my interpretation too.
