Most awkward and/or interesting anime couple?

Uryuu Minene (or "Ninth") and Nishijima from Mirai Nikki. For some reason this pairing just... did it for me, and I really did not expect them to be paired up with each other. Even in the OVA, although overall I didn't really enjoy it all that much, their ending together was what really made me smile. I would have put Yuno and Yuki, but their relationship was harder for me to follow and their ending in the OVA didn't make me light up the way these two did.
