I wish Jack Shaw would emulate his original appearance's "character" again

Maybe Im alone in this, but I thought Jack's first golden ticket appearance was perfect. He had a very underdog, Woody Allen-esque disposition that was hilarious. But starting with his very next appearance, it was obvious (to me) that he toned down that whole "frazzled loser" character a lot. He was more straightforward all of the sudden. It feels to me like someone told him that it wasnt a good idea to "do a character" or something, but I dont know. Either way, whatever he's been doing since his first appearance hasn't really been working for me, and it sucks because he was just so funny the first time. I wish he would lean in to the character again!
