Hee, funny! I loved watching the grouchy Clark go all caveman defending his (kinda-sorta but not really) partner and (kinda-sorta but not really) threatening him with all sorts of vaguely worded scenarios.
Loved that Lois was there to witness the rout. I could just see Clark looking (kinda-sorta but not really) guilty as he tried to explain. Lois's reaction was great, too. He's strange, yeah, but maybe that's a good thing. And undercover suveillance -- woo-hoo!

Of course, it'll be a while before they *really* get under the covers, I expect, but this was a good step in that direction.
