I liked it, personally. The ep, not the song. Although the babies' reactions to it were great.

Mr. Cake is not the father and he knows it.

Wow, I thought that was a really great episode =/ I mean, it showed Pinkie Pie in a more mature light. Very well done. ^^

I expected to dislike the episode since I don't really care for Pinkie's character, but I thought it was fantastic and had some great moments of comedy. Pinkie's been needing an episode like this.

I will agree with you on the pig song, though. This season just hasn't had any great Pinkie ditties so far.
