We love a good "woman in labor dances!" video [1], so if you're anything like us, you'll get a kick out of this one [2].

It features a woman named Ambz Shi Murphy dancing to cult hit "Baby Mama Anthem" at Waikato Hospital in New Zealand. We imagine that between twerks, she was likely having some serious contractions, but her dance moves — which are going viral with a half million views on Facebook already — look impressive by even non-nine-months-pregnant standards! Well done, mama.
