Peter's well aware of how stupid that joke was but it made Tony laugh and helped to dissolve the tension (or at least he hopes it did). He pulls his hand back and takes another drink of coffee.

he pulls the mug away and gives Tony a look. "Cut me some slack here, Mr Stark, I've only been awake for like thirty minutes!" If even that. He pulls his head back a little so Tony can't mess his hair, grumbling under his breath.

"I'll comb it later."
