Jimmy Fallon is very well known for his musical impressions; his Neil Young is out of this world. So, you'd be forgiven for thinking that the deck was stacked against Christina Aguilera when Fallon asked her to take part in a game of musical impressions with him last night on The Tonight Show. Though, the minute she started belting the "Folger's Coffee" jingle in Cher's signature contralto, Fallon must have known he was going to lose.

"this little piggy went wee wee..."

Aguilera's Cher was no match for her Britney Spears impression, however. The tone, the breathiness, the vocal ticks — they were all there. If you want to be impressed by someone signing the words "this little piggy went wee wee wee, all the way home," watching Aguilera's performance is a pretty good way to do just that.
