I like how Punk, in a way, addressed the the bags under his eyes in the Smackdown promo and is using them to show that 'he can't sleep at night.' More believable than if he came out there and said it with a fresh, well rested face.
Little things like this, when wrestlers make the effort, makes everything so much better.
This was a tweet he got after RAW
CM Punk @CMPunk
“ there is creams you can use for your puffy eye bags, just saying.” There ARE classes to take for your sad grammar, just saying.
So he knew people had definitely noticed them, next night "I can't sleep...."
