B.2. The Proposed CLoT is not Tailored for Humor Generation
In this paper, our primary focus is on exploring the Leap-of-Thought (LoT) capability of large language models, a crucial
cognitive skill akin to Chain-of-Thought [2, 3, 14–16], rather than humor generation per se. The selection of the Oogiri game
as the humor generation task in this study is justified on following three main grounds:

(1) The Oogiri game serves as an ideal platform for investigating the LLM’s LoT ability. As discussed in the related
works section, the Oogiri game aligns well with the characteristics of LoT, demanding players to think creatively outside the
box in response to multimodal information. Moreover, the three primary types within the Oogiri game (including I2T, T2T,
and IT2T) also align with the input and output types of multimodal LLMs. Hence, the Oogiri game proves highly suitable
for exploring the LoT capability of LLMs;
