Spike and Maggie are quite alike in some ways, aren't they? As in, batshit insane in the best way...

I think the swan would be the clear winner in the water, and the dog would have the edge on land - but it would be far too ugly either way. The displaying part was fun to see but you can believe I called Spike off before it got too intense. He may be a stroppy bastard but his saving grace is that he does always listen.
