Explanation
A group of people in black suits and sunglasses stand at what appears to be a funeral. One asks "Will that be enough?" and another responds "No, no. She would've wanted more. So much more." A third says "Very well, sir." The caption below reads: "When I die, I want parmesan grated on my corpse until my family says when."
The joke is a play on the familiar restaurant experience of having a waiter grate parmesan cheese on your pasta, always asking "say when" to indicate you have enough. The typical social dynamic is that people feel guilty stopping the waiter too soon or letting it go on too long. Here, the comic imagines someone so devoted to parmesan that they want this ritual performed on their dead body as a funeral rite. The solemn, Men-in-Black-style presentation of the funeral attendees contrasts absurdly with the trivial subject matter. The "she would've wanted more" line parodies the gravitas of honoring a loved one's final wishes, applied to an endlessly escalating pile of grated cheese. The humor is in the commitment to the bit -- treating an Olive Garden ritual with the seriousness of a sacred burial custom.
