That moment when you accidentally type in 900 instead of 90 into mechjeb and your rocket starts flipping around and exploding. That moment when you get a heavy duty mun base on the mun, and you forget to bring solar panels with you. That moment when you don't know what the button is to activate the EVA pack as Jebediah goes flying off towards the sun. That moment when your mouse dies while you're trying to configure MechJeb That moment when you chuck a hundred hitchhiker tanks full of kerbals at your ship to try to lower your periapsis to get pulled in by kerbin. That moment when you just realized that you made a 1km orbit around the moon with your kethane miner and that you can't time accelerate. That moment when you spy on the kraken and see it's actually a little boy that's barely 4 years old using Hyperedit on everybody's save files. That moment when you build a massive, awesome spaceplane with B9 Aerospace and realize that you used fuselages instead of fuel tanks. That moment when you think you've manually cleared your parts folder of all modded items and you find the only part in the game is the fugly Mk. 3 cockpit. (Seriously, how do you make that thing look good without editing its model?) That moment when the kraken turns Jebediah into Michael Jackson and Kerbin explodes in a firey rain of rainbow krakens.
