Window in Nero (CD burning program): “Are you sure you want to cancel burning the CD in the middle of the burn process? That could make the CD unusable. [CANCEL] / [STOP]“

Immediate thought: I don’t want to CANCEL the burning process, so I’m not going to press the button that says “CANCEL”. I’ll press the other button.

That turned out to be the button that STOPped the burning process and created a coaster. Burnination (has not been achieved)!
