"You remember that I'm only about ten stone, don't you?" Loki answered Sif, rolling his eyes, and then corrected for the terminally-American-weights-impaired – "Not even a hundred forty pounds, that is." Thor, of course, got jovially elbowed. "And I don't need more bruises than she's already given me, either! Watch those great big hamfisted fists of yours, would you?"
At least he could look at Sif and not imagine her in – well, other than she was at present, and he'd leave it at that, thanks.
