Turns out that Keith Richards was playing an April Fools prank when he said that he inhaled his pappy with a toot of coke.
But no one got it. He had to tell everyone it was a joke.
That is the funny part - the fact that Keith snorted his dad's ashes was more believable than the fact that he was joking.
Dude, I know how you feel. No one at work gets my jokes either.
