Yup, Littlefinger puts the "Ass" into class, ya gotta love 'im.
Agreed, Ned dumb like stick, great guy but wow, talk about doing absolutely nothing to achieve your 'noble goal' of putting the proper heir on the throne, other than just enough to get your ass arrested by the guy you're trying to usurp. Good lord, when Renly displays more political competentence than you, by simply running away...man, you deserves some prison lovin'.
Finally, the Dorthraki feel kind of menacing (and slightly more numerous than the ten guys on horses we've seen so far), loved the Drogo rant at the end...was hoping, however, for a 'hear da lamentation of der wemon' call-out, but ya can't have everything...
As to spears, no they are not really designed to be punched right through people, remembering that that is two thick layers of muscle, not to mention two layers of clothing and armour. They are really designed to poke really big holes in horses (or people if they're dumb enough to get in the way) inflicting a lot of damage on internal organs and disrupting the structural integrity of one of the big muscle walls, making it really hard to stand, let alone fight...they're also good for allowing tubs of bleeding, which also tends to ncapacitate quickly.
Having written all that I've just realized that your question was likely rhetorical and I look like a big nerd...or a really creepy guy.
