16. Rachel Dratch
If you tuned in to SNL on May 1st, 2004, you saw Dratch as Harry Potter, quaking under the spell of Lindsay Lohan's cleavage — then, a few minutes later, as Debbie Downer at Disney World. One of the best nights any SNL player has ever had. Dratch had no ego — just the will to try anything. Her Sheldon on "Wake Up Wakefield!" was an agonizing portrayal of adolescent overtrying, and only Dratch could make it so soulfully funny.
Greatest hit: Debbie Downer was unstoppable, kind of like feline AIDS. Which is the number-one killer of domestic cats!
