By WENN world entertainment news - Rolling Stones rocker Keith Richards insists he never snorted his father's ashes - his recent comments were made in "jest". The Gimme Shelter guitarist can't believe people took him seriously after he told music magazine NME he once snorted his dad Bert's ashes mixed with cocaine. He said, "He was cremated and I couldn't resist grinding him up with a little bit of blow. My dad wouldn't have cared. "It went down pretty well, and I'm still alive." However, Richard's manager Jane Rose tells MTV.com that the hellraiser's comments were "said in jest. Can't believe anyone took (it) seriously." That's a pretty f-ed up joke!
