I learned a new word thanks to vlogging

In an artist on artist vlog interview, John Cusack and Diablo Cody chat it up online talking about parties, work and their perspective on art. God only knows if their dialog is prepared and rehearsed at some point. I would never be able to keep a straight face and use the word "pastiche." Considering it's hard enough memorizing what it means, the only way I'm ever going to remember to use such a word to describe stuff like the late nite show version of a song's melodic violin similarites to Come on Irene is if I correlate it with the phrase "past ich".
