The sweet strains of Sir Mix-a-Lot immediately popped in our heads upon hearing the word that Kathleen the anaconda might be knocked up.

The New England Aquarium performed an ultrasound, but the results were inconclusive, so a vet will keep watching her. You can watch the Aquarium's footage of Kathleen getting her ultrasound over at the Aquarium site.

Kathleen and another female anaconda share space with a male anaconda who must be quite the babydaddy since the other female anaconda is already pregnant. To encourage the breeding, the Aquarium created "man-made rain and flooding" and provided extra food. No word yet if Barry White was piped in through the speakers.

When it's time for the other anaconda to give birth, they might have between 20 and 40 babies, according to the Nashville Zoo.
