We realized after filming that we never explained what "BYOK Dinner Party" Means. In keeping with SJ tradition of never explaining anything anyway, we were originally gonna leave it up in the air. However, for comedic value in future episodes, it might benefit you all to know that BYOK stands for "Bring Your Own Knives", thus Jim mentioning at the end of Episode 8 how the three friends will "need these knives" where they're going. Brilliant.
