Nope. Best singout ever was Leslie Hunt (season 6, semis week 2). After being in the bottom with Jordin Sparks (!) and then eliminated, Leslie seemed to take her [not unexpected] elimination easily and did a version of the Pussycat Dolls' "Feelin' Good" similar to her previous one until the end, when she unexpectedly said/sang "Why did I decide to scat? America don't like jazz.." just as she was cut off. The show could go 20 more seasons without anybody ever topping this!
