Hmm, let's dip a toe in here...
On the "conventional" side:
The Alexander brothers - they so love to pick on one another... makes me sorry I am an only child
Hamish and Tom Caparelli and how that one developed over the years - and they still have so much boyish bravado despite being almost a hundred years old
Kevin and Ginny Usher - that one is... well ... let's say the Mexicans are probably capable to do it some justice, in 150 episodes or more
Although there might be some unintentional consequences considering the Kleenex supply /possibly blood pressure too/ of certain people...
*determinedly,if not entirely succesfully tries not to look at
roseandheather*
A slightly ... well, actually a very unconventional one, although I am surprised how our
s and
s missed it :
Shannon and computers /well any machinery, especially of the military type/ - that is a magical, mystical union of unknowable origins, unimaginable power and consequences I am afraid even to dream about.
. Not to mention that a simple, harmless "Oops" can bring me to uncontrollable shudders just like that.
