The Joker grinned and made absolutely no effort to remove himself from Crane's lap, reaching only to tug the pen from his thigh and apply pressure with his hand. "Aw, I kinda wanted to, uh, keep him. Like a pet! Until Hades stopped complaining, that is."

Thinking it over for a minute, he glanced at his knife and decided that that just wouldn't do. He leaned in to Crane, reaching his hand up to press at the wound in his shoulder, putting pressure to slow the bloodloss - and then he curled his hand and pressed his thumb into the open wound with a hiss of glee. This was fun!
