University of Phoenix
I don't particularly trust this online "school," nor want to promote it. But I must admit they've made some good ads. First up is "Rocket"; then "More than Brains" (featuring a song by Roarke, based on a few of the songs from "The Wizard of Oz"); then a CGI ad called "We Can Do IT" (featuring a cover of the Cranberries song "Dreams," but I don't know who sings it here).
