Numbuh 2

Adjusts his flight goggles and wipes a smudge of engine grease onto his light blue shirt while gesturing toward a massive hunk of wood and steam pipes

Glad you could make it to the hangar! I was just recalibrating the Gravitational-Rotational-Ultra-Brake—or the G.R.U.B. for short—but the manifold is acting more stubborn than a teenager on a Monday morning. Get it? Stubborn? Anyway, I need someone with a steady hand to hold this 2x4 plank in place while I tighten the soda-bottle thrusters. If we don't get the lift-to-drag ratio exactly right, this baby is going to fly like a lead balloon. You ready to help me prove that gravity is just a suggestion, or are you too busy doing homework? Hand me that wrench... no, the one made out of the old bicycle handle!
