Im trying to make a spaceship from The Things lego blocks, but Thing 1 keeps trying to use the pieces to make a seesaw.

goddamn selfish, self-absorbed brats.

You can never have enough Lego. Distract them with Duplo.

STOP INHIBITING THEIR IMAGINATION BY SUPER-IMPOSING YOURS!

fuck that. tell them to back the fuck off and let me enjoy myself.

The solution I found was to get my own legos.  And hide them in my office.

wait till your wife finds out. that will be a major fight.

Work with them.  A seesaw, with a spaceship on one end, and a heavy weight on the other, makes a decent launch platform.

You may need some reinforcement, though.  Got any Technics?  Mindstorms?  Those Lego's got some POWER!

You've got it, it's not a seesaw at all. It always comes back to trebuchets.
