Why you people can't find anything better to do eh?
Okay, since you wanna play this game, here is my take.
Starting from the hardest.
Obviously, it would be playing the op, and the facile easy sonata.
Reading Ulysees is next because anyone can read it. Comprehension wasn't mentioned.
Scraping gum would be next, since it is annoying.
Trying to not punch someone is according to context. Depends on who you are with.
Typing next
Opus cum.....clav......icc.....cum.....cumba.........Opus clavicembalisticum.
Eating is pleasurable.
