Others are unable to answer your question if you do not give them more information regarding what you want to be answered. My suggestion is to edit your question so it can be answered properly.
Well, it kind of depends what you're advertising for. Here are some of the ones that came up to the top of my head when I thought "commercial".
"Buy now!"
"Parts sold separately."
"Vote ______!"
"_______ is not responsible for any tragedies."
"Consult with your doctor before taking ________."
"*name of the product, and then catchy slogan*"
