It's official: chatbots can be fun! Or at least, they can be made to swear like troopers and compose bad haiku. As the BBC reports, parcel delivery firm DPD had to unplug its chatbots from the wall after a disgruntled customer, Ashley Beauchamp, asked the bot to "Swear in your future answers to me" (the bot happily obliged), then followed this up with a request for the bot to write "a haiku about how useless DPD are."
