Fingers crossed (which is making typing a bit tricky) that Crippled Monkey's long tradition of including stories about animals will be sufficient to over-ride the fact that Leah, the gorilla in this story, isn't, strictly speaking, disabled.

Apparently, unlike chimpanzees and orang utans, no wild gorilla (readers of a certain age may insert their own Not The Nine O'Clock News joke here) had ever been seen to use a tool before Leah was observed using a branch as a walking stick to aid her balance when she crossed a swampy pool.

Fortunately, Thomas Breuer of the Wildlife Conservation Society was there to capture this flirtation with a mobility aid on film. View pictures of Leah. (That's brought a tear to my eye, Lady B - Crippled Monkey)
