There has been several, but one recent one was in Portal 2 boss fight.
When you have to attach the first core, I, for some reason, thought I'd have to put it where the main core is, and wasted several attempts in that.
Also any battle with a time limit is going to make me panic anyway.
So I got to hear the Space Core being happy about SPACE!!! for many, many, aggravating attempts. So I very much came to hate the little bugger and wanted to kick his little metal butt straight to the moon.
I was embarrased by how bad I was at the final encounter.
One was the last core. I thought there was some catwalk you had to go to, not jumping off a catwalk into a portal.
The second was hitting the failsafe button. I must've been running around for ten minutes, until I saw you had to stick a portal on the ceiling in the failsafe room. I felt so stupid.
