There was a hipster joke here, but it got old and had to be replaced.

"Come real close and tell me it's fake. I dare you. Did you notice what appears to be a switchblade under my lower hand?" (via redditor steamviking)

This picture was posted to reddit with the title " So my dad got his hip replaced and had the doctor save it so he could turn it into a cane." What followed next was predictable: he was told by people claiming to be doctors on the Internet that this is impossible. In light of recent studies showing that people are more likely to trust fake doctors in comment sections than real doctors in real life, I'm not inclined to believe anyone.
