The joke is that the user is asked for their mother’s maiden name, and they think it’s a website/application on the laptop. However, it’s actually the laptop itself that’s asking. The laptop then starts romancing the user’s mother, telling the user that their mother’s maiden name won’t remain that for long, presumably because the laptop plans on marrying the mother.

As @agamemnonymous@sh.itjust.works points out, that’s not actually how maiden names work though. Your maiden name stays the same before and after marriage, it’s your last name that changes.

I think the joke would’ve worked better if the user responded “She doesn’t have one” and the laptop replied “She will soon!!” or something like that.
