You can't always be logical

I swear one of the best animes of all times would be Gintama. It is full of rubbish, does not have a plot, and even the mangaka doesn't know what he's doing with it when the fans asked him. But anyway, you need a little bit of insanity to really destress.

For example:

Gintama Episode 109: A hopeless member of the police force is working undercover to join the local resistance force, known as the Jouishishi that is still present, in the hopes to crush down from the inside. So apparently he had to go through an interview, and then a written question and they show him going through the process. Here's the question:

Examiner (also the head of Jouishishi who's another idiot. Actually, they're all idiots): next up are maths questions.

undercover agent Yamamoto: This is bad! I haven't answered anything correctly yet..

Examiner: Question: 10 Shinsengumi members and 6 Jouishishi square off on a road. A charging Shinsengumi kills three Jouishishi. The tireless Jouishishi then killed two Shinsengumi members. In the midst of the chaos, two Shinsengumi were injured. However, six additional men join in as reinforcements. Two more Jouishishi were taken down....
