After a bear jumps a guard rail in Colorado, it begins climbing a very steep dirt wall. The bear quickly realizes it has its work cut out for it when it can't seem to get a good grip on the vertical wall and begins sliding back down. After multiple valiant attempts, the bear eventually tumbles down again and finally cuts its losses. But hey, at least it gave a solid effort. 

Speaking of solid efforts, drone footage from South Africa shows a wild baboon making a run for it across some building tops as its habitat is encroached upon by humans. That's one animal that may be hard to catch.
