Who does a better Acid Trip? Richard Pryor or Jack Black?

Have you ever seen Richard Pryor doing an acid trip in his stand-up act? He slowed his body down and altered his voice in a pretty hilarious interaction with a white hippy Acid dealer. Jack Black's acid trip is totally different, but he's trippy too. Which one do you like better, even though they're completely different? I dig Richard Pryor's better even though I love Jack Black's crazed humor, too. But it isn't as hard edge as Pryor back when he was an angry young guy with a racial attitude that was previously only breached by Redd Foxx. I dug Jack's interaction with Kyle Gass much better in the field of ganja. Does that peg me as an old guy?
