Kopi Luwak is a totally real thing that I actually got for my dad for fathers day over a year ago. I hate coffee myself so I never got around to trying it, but I heard that it was much less bitter taken black than normal coffee.
However, it is procured from the feces of the Asian Palm Civet, and not lemurs as Todd seems to think. Remembering species is hard for Todd, and lemurs are just way funnier.
It is also definitely the most expensive coffee ever. 200 grams of it costs about 60 bucks on amazon.
