I guess when I watched it the first time I had already completed all the vocab and kanji on JCJP. It probably would be better to watch the English sub actually, especially so you can find out what they were actually saying in the bit you watched. ^^
The drama is called 日本人の知らない日本語 (Nihonjin no Shiranai Nihongo). I forgot to say the title before so would have been harder to search for an English subbed version.
Here's an english sub. Enjoy!
