I was loving the way Kif didn't know who the babys father (if that's what you can call it) was because of the crazy alien way in which he becomes pregnant. But besides that, this instalment doesn't have much going for it at all.
Any funny parts are in the first half where Kiff first gets knocked up a notch and then the episode feels like it has to drag this idea out to full length, forgetting it's supposed to be funny along the way.
It's a shame that zap Brannigan and Bender are both here through the whole thing but just aren't raising a chuckle. Plus, there's way too much unfunny talk from some alien helping with the birth in the later parts.
