Well at least you didn't crack the drive way!,, no really, many of us that have been around this business for a while, have had the experiance, you should be able to go in the darkroom and slowly remove the film from the camera, and roll back into the canister, as Jeremy said.
I have lost 2, 80-200mm f/2.8's over the years, one is at the bottom of Yellowstone Lake and the other is at the bottom of a canyon in Glacier National Park, so unfortunately it does happen.
Let us know how the photos come out.
