I'd have to say...myself and Burrahobbit because we detest each other and each other's worldviews. In short we don't get along together.
Or maybe my self and any Noob who starts to talke about how hot Legoas is, then I just wanna rip off their bubbley fangirl heads.
SPM and Hookbill are rather a bad pair as well since they are both caustic wits who ofen end up on opposing sides of the argumet.
