Here is Australian hurdler Michelle Jenneke's warm-up dance at the world junior championships on Sunday. "She's certainly happy about performing here," narrated the BBC announcer, wiping flop sweat off of his brow and tugging at his suddenly too-tight collar.

After the sexy dance, Jenneke jumped over a series of horizontal bars in close succession. Notably, she jumped over the bars considerably faster than the other women who had apparently been standing on either side of her prior to the race, while she was shimmying.
