The most asshole things our cat has done...hmm.
She hooked my hand with her front paw (without claws) while sitting on her cat tree 'cause she wanted to lick the condensation off the side of my glass. She'll dring water out of her fountain, but she loves condensation so we use it as a treat.
She'll walk in front of my wife when she's watching something on her tablet when she wants attention.
She'll lick my hands while I'm playing the EA NHL game du jure.
But really for the most part she just does her own thing--only really scractches her cat tree and the scracthing pads/post, hasn't missed her litter box, doesn't bite or claw, goes after insects/spiders in the house, is perfectly content sitting with us when we watch TV, doesn't gorge herself so we can use an auto-feeder/waterer, and sleeps at the foot of the bed.
