* After successfully landing on Mun in one of his [=LPs=] of Kerbal Space Program, "One Giant Leap for Kerbal Kind", Kurt has the Kerbal go on EVA and messes around with the EVA Pack a little. After getting a bit too far away from the shuttle for comfort, Kurt begins to pilot the Kerbonaut back. In mid-flight, [[HilarityEnsues Sticky Keys activates]] and Kurt loses control while trying to cancel the function, causing the Kerbal to collide with the ground and bounce into the air numerous times before grinding to a halt unharmed.
--> '''Kurt:''' Oh, no! Oh, no! He's gonna die!

* The entirety of Kurt trying to make a Space Shuttle in KSP. It does not end well.
* The ending of the "Buzz Cut" video, specifically Kurt's signoff.
--> '''Kurt:''' My name's Kurt, I'm gonna go cry in a corner now, bye!
* During [[https://www.youtube.com/watch?v=MUSBxFE56sY Episode 44]] of his ''KSP'' series, for the first launch of his Solar Explorer rocket:
-->''Kurt notices he forgot to add reinforcing struts between two stages on the Solar Explorer.''
-->'''Kurt''': [[GoshDangItToHeck Oh, sugar!]] I forgot to put some struts between these two stages. Hopefully that's not much of an issue... [[TemptingFate That's a little bit of cause for concern, but I think we should be OK.]]
-->''Later, as the bottom stage begins to plow through the rest of the rocket above it...''
-->'''Kurt''': What ''[[OOCIsSeriousBusiness the hell's]] '''[[SuddenlyShouting happening?!]]'''''
-->''The rocket explodes.''
-->'''Kurt''': Back to the drawing board, I think...
* In episode of 71 of [=FLoB=], Kurt finds a glitch where he finds water floating in a block space and not flowing into a cavern. Upon unleashing the water, [[TooDumbToLive Wolfie immediately jumps into the pit]] and only survives due to the water now flowing into the pit, causing Kurt to momentarily panic.
