I played two years ago the 5 Sarcasms, op. 17 by Prokofiev. These pieces are not hard to play and they are funny. I really enjoyed play this pieces. Also, when I performed them in concert, the people seemed to like that. Someone played them at the Montreal international piano competition this month. Also, I like the op. 4 # 4, that is "Sugestion diabolique", also by Prokofiev. This is a cool piece too !
