I understood you, as well, and saw the joke. And I did originally mean fencing foils. Because katanas are much sturdier. I just thought I'd go in a different direction, because funny. To me, anyway. I mean, what could be more disjoint than katanas instead of Mai Tais. Unless there's a cocktail called the katana, which there probably is, which undermines the joke, so...I fail.
Hilariously, hilariously fail.
