I hate K'nex, or "I'm not a toy-making elf, dammit."

Yes, big brother, I can put toys together. Yes, nephew, that means yours. If asked nicely, I'll do it for you. But damn it, plopping a K'nex set in front of me does _not_ constitute "asking nicely". And I don't like K'nex or anything not Lego. Legos, you can pull apart fairly easily; no harm done. Not K'nex. Oh no. You screw up there, they're stuck _good_, and you can't pull _too_ hard or the cheap fricking plastic'll break. I hate K'nex.

The lesson to be learned? If the kid says he's got something for you, _don't look to see what it is_. Also, parents can be blindingly stupid at times. If the kid can't assemble it himself, why the _hell_ are you buying this for him, brother?! >.
