Have you ever felt like you were talking to a wall. The person you are talking to just doesn't seem to listen. That's what happens to this little boy when he tries to tell his phone app "Robi" a knock-knock joke. Robi does not want to listen.

You see that he gets a little frustrated and even his brother jumps in and tells Robi he needs to listen. (Think they've heard those words before?) Mom steps in to try to help too, alas Robi just won't cooperate. The kid has patients is all I have to say.
