Title text: Can't and shouldn't.
In this comic, "could not reproduce" is a double entendre. Because the reported bug is that speech recognition failed on a young child's voice, the programming team attempt to reproduce (biologically) in order to have a child to use as a test subject to understand and fix the bug, starting by reproducing it (the bug). However the attempt fails, as shown by the negative pregnancy test, and therefore the bug report is closed with the reason being "could not reproduce": they could not reproduce the bug because they could not reproduce biologically.
This reason also shows up in comic 937: TornadoGuard.
The title-text "Can't and shouldn't" qualifies the bug report, meaning that the programmers cannot and should not reproduce given their unacceptable motive as well as poor child-rearing skills (demonstrated in comic 674: Natural Parenting).add a comment!
