Now there is a real life version for you to try.
New Zealand Police have been inundated with suggestions after asking people to help them name their latest recruit - a purebred German shepherd puppy that will join the southern force.
In a Facebook post, Dunedin police have asked for names starting with the letter K.
They have received hundreds of suggestions, not all of which start with K, and will release a shortlist early next week.
The post has 10,890 likes and 982 people have shared it.
"He is so cute if he does not work out can I have him????," one person posted.
Suggestions included Kuddles, Kopper, Kipper, Kamander, Kinko, Koko, Knasher, Kdog, Krypton, Katcha, Kadett and simply K.
K9 was a popular choice and King Kong got a mention.Kitty seemed to be a long shot.
