Keith Richards has a dying wish, a very fitting dying wish ... that his daughters Theodora, 30, and Alexandra, 28, snort his ashes after he dies.
Yep, just like a line of coke.
It's kind of a family tradition ... the Rolling Stones guitarist -- who battled cocaine and heroin addiction -- infamously admitted snorting his own father's cremated remains in a 2007 interview.
As for how the 71-year-old wants his daughters to get him up their nostrils ... Keith says he'll gladly supply the straw. Coolest dad ever?
