In the episode 4 of the second season they keep laughing randomly when words like "skull" etc are uttered. I don't understand the rationale behind it.

Note- I am watching Japanese audio, English subs.

    I think they're just being weird to break up tense situations. The words Ritsu says are 髑髏【しゃれこうべ】 "skull" and リコピン "lycopene", apparently.These words sound a little bit intrinsically amusing to me, I guess? See also: detail.chiebukuro.yahoo.co.jp/qa/question_detail/q1040907955

  • Recently watched the 3rd school festival episode. It was a very emotional moment, but the writers broke it up very well with 'lycopene', I wonder if the field trip episode reference was to set up this moment. Anyways, it was one of the strongest anime moments for me. Arigato, sensei @senshin chan. Feb 6, 2017 at 18:55
  • the joke is that Ritsu is imitating Kansai's accent, so she throws words at random but with that accent.

I'm Japanese but it's incomprehensible little bit to me too. 髑髏 (しゃれこうべ) is not usual word in these days and sounds little bit strange (goofy, should I say?). We use 頭蓋骨(ずがいこつ)to mean "skull".

It's just a joke without any reason. but somehow it's funny in certain situation, like tense situation or lifted up at midnight on trip. Because, there's no reason.
