God-Emperor he may be, but even Leto II isn't immune to being funny and to specific people's humor.
Leto II grew so bored chatting with the first Duncan Idaho in the novel that his mind withdrew to his inner thoughts completely being unaware of the real world. Leto II even goes on an internal monologue.
Leto II: I am forced to block them off though. There is no sense dwelling on them. They now are little more than poignant reminders. As is this Duncan who stands in front of me with his lasgun... GREAT GODS BELOW HE HAS CAUGHT ME NAPPING. He has the lasgun in his hand and it is pointing at my face! Leto II: You, Duncan! Have you betrayed me too? Seems Leto II had to keep up his God-Emperor appearances even if he knows he fucked up.
Leto musing over having a "gross protuberance" made to wear so as to screw with people who examine his worm-body for genitals.
