Larry, Moe and Curly come to mind. They are always picking on each other and yet, if push came to shove, they'd be there with bells on to defend the other. I can see them all, glow sticks in hand, swinging them randomly at each other, like the swords they wish them to be, as tho' they were swashbucklers fighting the evil pirates. And then, in their endeavors, with their arms outstretched, attempting to stab/swat the other with their "swords", they each end up knocking themselves out landing on the other mischievishly laughing. And then the older brother begins reprimanding the younger ones as tho' he, himself, hadn't a thing to do with the discord....
BRUHAHAHAHAHAHAHAHAHAHAHAHAHA! Keep it up boys..........The world is full of comediens. But most of them don't come in three's.
