https://twitter.com/OGNGN_UC/status/1611633317132242944Larry can't keep food off his mind while Hassel's lecturing him, and he lies to Hassel that he's thinking of the lecture when asked what he's thinking about. He can't stop thinking about food, though, so the concept of eating and Hassel's lecture mixes together.
He ends up talking about how much he'd like to eat Hassel, and that he'd like to eat him with some lemon, and terrified Hassel is wondering out loud if Larry's speaking of some sort of a metaphor.
