Considering that even the biggest stars “SNL” has ever produced only have one ‘Best of’ collection to their names, it’s a testament to Will Ferrell’s versatility that Universal is giving him his third compilation (well, that and the fact that Ferrell is bar none the biggest star “SNL” has produced in 20 years). From the looks of “The Best of Will Ferrell, Vol. III,” however, it’s starting to look like they may be coming close to the bottom of the well. The set is funny, mind you – it includes arguably the best cheerleader skit of all, at the chess match – and you can never go wrong with a “Celebrity Jeopardy” skit. They even include the oddball “Do You Like Luxury?” skit, which only Ferrell could make funny. However, the inclusion of a “Lawrence Welk” skit is a big minus (that should have been saved for a “Best of Kristen Wiig” DVD, God help us), and the “Inside the Actor’s Studio” skits are only as good as the honoree, and while Abby Elliott has her good points, her Drew Barrymore impression does not leave much of a…well, you know. The warm-up performance of Green Day singing “East Jesus Nowhere,” with Ferrell rocking the cowbell and even taunting Billie Joe (“Does this song ever end?”), is a great extra, though. Pity they couldn’t get him to do an audio commentary; those have always been as entertaining on the other best-of DVDs as the skits themselves.
