But Breja's thread DOES contain a problem: the fact that a problem thread doesn't have a problem IS the problem. Problem with that problem thread is that if you provide a solution then it's no longer a problem, and thus it wasn't a problem in the first place, or something like that which opens a rift in the space-time continuum. Kinda like going back in time to kill your grandfather.
Though why you'd want to kill your grandfather is beyond me. He seemed like a nice enough guy, minus the yelling about kids on his lawn. But hey, don't they all do that at least once?
Grandma, tho - she was a piece of work, let me tell ya! Complete nag, and I'd understand you wanting to kill her. And it wouldn't cause the time paradox since your grandpa was cheating on her anyway, what with the affair he was having with schoolmarm O'Leary. Ms. O'Leary was quite the beauty, too! She put the "ass" in "Fine Irish Lass".
So fine she was, Ms. O'Leary insprired the pickup line: you must be from Ireland, because my penis is Dublin.
