When Logan passes out from his injuries, the front desk lady brought her veterinary student grandson to patch him up. It's a Wolverine, after all! When Logan offers to shake the young vet's hand, the latter backs away in terror because Wolverine apparently unsheathed his claws and hurt him while unconscious mid-surgery.
Logan's entire bath-and-shave hygiene session in the Yashida residence. He later quips, "I've been violated."
There's some Bilingual Bonus as well that makes it even more hilarious. One of the ladies says: "It feels good, right?" ("Kimochii deshou?").
Not to mention Hugh Jackman's remarkable performace making it look a lot like trying to bathe a cat in general.
Logan sticks the chopsticks upright into his food. After Mariko gently corrects him, he did it again!
While on the bullet train, Logan tricks a yakuza to jump to avoid being struck by a low-hanging sign, only for the unlucky bastard to get struck by a higher up sign.
Also in the traintop battle, the brief cut to Mariko in her headphones while a Yakuza roars at the glass in impotent rage.
And before that, Logam enjoying the reclining train seat.
When the guards freak out over Logan setting off their metal detectors, he tells them with a completely straight face, "I had a hip replacement."
