Further spurring rumors I whispered to myself on the subway last week about how Rob Kardashian actually spent the last year chained to an elliptical machine in a basement somewhere in Calabasas, the forgotten son finally resurfaced Sunday with what appears to be a sincere plea for help.

After deleting all his photos, the former sock kingpin posted an Instagram picture this weekend with a bone-chilling message attached for Kanye: watch out for the bitch!!!!!!!

Caption: "This is my sister kim, the bitch from Gone Girl,,,"

Despite the strange implication that Kim is a psychotic narcissist and potential murderess, the photo was posted from an account identified as Rob's with more than 2.7 million followers attached. The family does not appear to have addressed the post or its allegations.

Still... might not be a bad idea to have someone do a wellness check on Kris Humphries.
