Dentist? - 日本語のビデオ

 

This ビデオ by the サンドイッチマン is a funny comedic bit about a man who goes to see an interesting dentist.

口 is a word used a lot here alongside the phrase「口をあけて」。"Open your mouth"

「またまた」is also a cool phrase that our dentist character says. I learned that it's another way of saying again and again with an annoying tone. 

「サメ」is also a noun that I learned meant shark.

There is also some good examples of casual speech like「お金ないから…」
