This is one you likely won't see from Mitt Romney.

Samuel L. Jackson stars in a short film, "Wake the F--k up," supporting the Obama campaign and urging people to vote, preferably for the president.

The ad, paid for by the Jewish Council for Education and Research - Alexander Soros' Super PAC that brought you Sarah Silverman's equally NSFW voter fraud spot, was written by Adam Mansbach, who also penned a hit children's book for adults called "Go the F--k to Sleep."

And Jackson, as he is know for in his films, drops plenty of F-bombs. So it's plenty not safe for work. See it after the jump.
