To enroll in a class, show up to the first two months of the class, then willingly withdrawal from the class. Oftentimes a person is inclinded to reichmanning the same class over and over again.

Ya you know, I was gonna graduate early, but then I had to take quantum physics, and all I could do was Reichmann it.

Rachmaninoff Concerto 

hand and ball breaking music that destroys your hands and is like almost impossible to play at the original tempo, only god valentina lisitsa gets close, also the chords are so huge like wtf i cant reach 13's! the second piano concerto is the most popular one overshadowing the 1st and 3th and 4th, didnt even know there was a 4th, also its one of the most romantical pieces of music and it makes me cum everytime i hear it

Pianist 1: Hey what repertoire are you learning?
Pianist 2:Rachmaninoff concerto.
Pianist 1: My best wishes for your balls.
