My workplace has a project titled Angry Kitten, and I chuckle every time I hear someone reference it.
“Who has been working with Angry Kitten?”
“The customer wants to know who’s the [document] feeder for Angry Kitten.”
“Angry Kitten hasn’t been getting enough attention lately.”
“Angry Kitten is going to be growing soon.”
(You can search for the project name to learn who the customer is, if you’re curious.)
