speaking of gundams, which ones are the must watch? (I've only seen Gundam Wing and that was when I was around ten)
I would recommend G Gundam and the original Mobile Suit Gundam. You might also like SEED. I would strongly advise against the following four Gundam shows: 0083: Stardust Memory, Gundam SEED Destiny, Gundam AGE and Gundam 00 in that order.
Zeta Gundam wasn't everything I'd expected, but it's by no means bad, and its sequel, ZZ Gundam has been pretty enjoyable so far. 08th MS Team is okay. Also definitely War in the Pocket. But 8th MS and WitP shouldn't be watched until you've seen MSG.

So somehow, even with all the anal sex jokes bouncing around, they manage to make this into a fairly touching episode about what happens when your spouse finds out about your ex, angry best friends, and also some nebulous plot development. It also answers the question of what is it like for a boy to pilot a woman shaped robot. The answer is very awkward.
And apparently, in spite of being a military trained soldier, Chiziru thinks its okay to go butt first through an opening.
