So as literally every human on the planet Earth is now aware, the 'Back to the Future' films recently celebrated their 25th anniversary, and did so with a ton of fanfare alongside new DVD / Blu-ray editions of the trilogy and even an intermittent theatrical run (only 25 years until the memorial re-release of 'Welcome to the Rileys!'). Even 'Saturday Night Live' joined in on the fun, using the occasion to deliver the show's biggest laughs in a long time.

The 'SNL' bit -- which popped up twice during the show -- may have been an obvious one, but it displayed some seriously honed comic gifts and was hilarious for 'BTTF' fans and non-fans, alike. Perhaps inspired by that footage of Eric Stoltz as Marty McFly , the bit dared to imagine what it might look like if other icons of the 1980s had auditioned for the film, and the impersonations in these mock screen tests are frighteningly good. Bill Hader's take on Alan Alda is worthy of a Nobel Prize (they might not award Nobel Prizes for impersonations yet, but it's only a matter of time).

Other uncanny moments include Hader's take on how Al Pacino might read one of Doc Brown's most famous lines, and Kenan Thompson as Bill Cosby as Christopher Lloyd. Jon Hamm even acquits himself nicely as the sketch's inevitable Robin Williams. So follow the jump to see the clips for yourself -- your day needs this.
