Original post, 2/24: Further proof Jimmy Fallon rigs the games on his show for his (and fine—the audience's) entertainment: Christina Aguilera sang "This Little Piggy" in Britney Spears's voice Monday night, and it was a random mishmash of things that turned out all right in the end. To quote Jimmy as he giggled delightfully while giving Christina a standing ovation: "Oh my God. That was something I've always wanted. That was amazing!"
