Obi-Wan Kenobi is basically a walking, snarkingfunny moment in these books, especially when interacting with Anakin and Bail Organa, who are no slouches in the snark department themselves.
Anakin pestering Obi-Wan until he gives in and reveals the full nature of the injuries he received in the terrorist attack.
Anakin: So. What was the damage?
Obi-Wan (evasively): Various bumps and bruises. Abit of scorching. A cut here and there.
Obi-Wan (uncomfortable): And really, there is no need to make a fuss. I hardly think I look at death's door. Do you?
Anakin: Not now you don't. But then, everyone knows Master Vokara Che is a genius. So- what else?
Obi-Wan (mumbling): Concussion. Broken hand. Broken leg. Broken shoulder. Cracked pelvis. Four broken ribs and a punctured lung. One or two internal organs jostled a bit.
Anakin (Sarcasm Mode): Is that all? And to think I thought it was actually serious. That should teach me to overreact.
Obi-Wan's reaction to Bail's protestation that Lanteeb won't be as bad as Zigoola is both hilarious and provokes a ridiculous mental image.
Bail: Have you ever heard of a planet called Lanteeb?
Obi-Wan: We are not having this conversation. At this very moment I am asleep in the Jedi Temple having a nightmare.
Bail: Hey, it's not that bad. I happen to know where Lanteeb is and it's nowhere near Wild Space. It's a back-world of the Outer Rim.
Obi-Wan: And that, of course, makes things so much better. We should take the entire Jedi Council there for a picnic.
In Stealth, first a clone medic, then Anakin, then Admiral Yularen and then Bail Organa all make the mistake of making a fuss about Obi-Wan's injuries, causing a long progression of funny moments as he gets increasingly more irate. Let's just say that Obi-Wan really hates showing any signs of weakness.
Bail Organa deciding to confront Obi-Wan about how awful he looks whilst he is driving, so that Obi-Wan doesn't pitch him over the side of the speeder. He then threatens to throw Obi-Wan out of the speeder if he continues to claim that he's fine.
Bail warns Obi-Wan not to take more out of his bank account than he has in (in other words, don't over-exhaust himself). Obi-Wan tells him that Jedi don't have bank accounts.
