Megamorphix OLL and PLL Parity | Intuitive Algorithms 

Watch the video before seeing the algorithms so that you understand them and don't have to memorize anything! These cases don't scramble the cube so I'm very happy to have discovered them! :)
ALGORITMOS
OLL Parity
(F R' F' R) u' (R U R') (F R' F' R) u U2 (R U R')
Alternatives OLL Parity
(F' L F L') u (L' U' L) (F' L F L') u' U2 (L' U' L)
(R U' R') u' U2 (R' F R F') (R U' R') u (R' F R F')
PLL Parity
(U R U) y' l' U (r U r' U' r' F r2 U' r' U' r U r' F') U' l y (U' R' U')
