That's mean yo.
Do you have a father? What if your father was super busy 24/7 and the only time you ever saw him, he was already too tired to spend time with you?
The prankster part, yeah it is justified because he wants to get his father's attention, and he probably can't get it until he does something that would harm his father's reputation. IT has to end now though, I would assume after that talk Naruto had with Bolt. Because, Naruto kept playing pranks to get people's attention (and he realized that the only way to do that was to become someone admirable), whilst Bolt wanted to get his fathers attention (which I'm assuming he will grow out of once he realizes his father's words in 700(.
/Bolt > Gokage
Set up a trap right under their noses while protection ensued. Hokage level Genin, GG.
