Look, we all know that hot dogs and bologna and the like are bad for you. Kids eat it and then get cancer later in life. We get that. Is it really necessary, though, to make PSAs like this one (from the Cancer Project) this horrific? It's not like anybody who sees it can take it upon themselves to change the school lunch program. Sometimes we don't know which is worse: the problems or the exploitative efforts of advertising agencies to eradicate them.
