Among his limited range of cliches, Randy Jackson once again invoked his tired line “Dude, you can sing the phone book” on tonight’s “American Idol” finale. He’s now said it in the last few weeks to both David Cook and David Archuleta. Hopefully, when they go on the Idols tour this summer, there will be a radio or TV host somewhere smart enough to actually challenge one or both of these guys to sing from the Yellow Pages.

As for the competition, while David Cook will undoubtedly have the better career boost from the show, it’ll take him a lot to overcome Archuleta’s teen fan base after the latter’s reprise of “Imagine” to close the show.
