Found a good video of comedian バカリズム, which Japanese-learners may find interesting. I don't want to explain much beforehand. You guys can just watch it and ask questions or make comments later on.
Thread title, which is also the title of the first half of the comedy, means
"The top 5 hiragana that look like they will come back if you throw them."
The last half is called "100円玉がとりにくそうな「漢字」ベスト5", meaning "The top 5 kanji that make it hard for you to reach the 100-yen coin".
A key word is 最下位（さいかい）= the last place in the rankings.
Hope you enjoy this but one never knows as humor isn't always universal.
