Sweden’s Simone Giertz has made a career out of making robots that are seemingly designed to do a singular function, but are really made to only kind of do that one function in the quest to bring joy to all. 

Giertz has a very popular YouTube channel where you can see a drone try to cut hair, a robot that can argue with the Internet, and more.

This week, she got to show off her wares to Stephen Colbert and The Late Show and it was a whole bunch of fun.

You’ll also be surprised to know that CBS censors curse words in foreign languages.
