We were a little skeptical of the "Insta-Dance" concept on Dancing with the Stars, but the humor and spontaneity actually went a long way. Funny how that works.

In terms of performances, last week's comeback kid Jennifer Grey is an underdog no more, quickstepping to a 27 and pulling off an instant rumba that was perfect.

Seriously, she managed a perfect 30 for the instant dance round!

Can anyone stop Jennifer Grey and Derek Hough?

Brandy, perhaps her chief competition for the title, pulled out another strong performance with a waltz that showcased her abilities. The crowd was really getting into it by then.

Kyle Massey, meanwhile, came alive with a gorgeous waltz of his own, then jived with an instant dance that was nearly perfect in its own right. The kid's a serious contender!

Kurt Warner and Anna Trebunskya have been climbing each week (albeit through attrition) but his performances deserve due credit as well. His waltz was actually pretty good.

As for Bristol Palin, her attempt at a sexy tango, but the intensity was lacking. Still, the girl went and gave it her all, and while her instant dance was lackluster, we love the effort.

The Dancing With the Stars leaderboard:

Brandy & Maksim Chmerkovskiy: 29, 28 (57)
