Peter's eyebrows raise to almost be hidden by his currently messy fringe, thoroughly thrilled by his ability to impress the other, ok he could die happy now. He looks around for a moment, trying to map a way down without breaking something and seems to pause in thought before looking at Tony a ghost of a frown on his face.

"Well, when you put it that way, how am I supposed to say no?"

He turns around and shifts so he can grab the edge he's sitting on and dangle from it for a moment, this is going to hurt, this is really going to hurt, he lets go, sliding down the wall, keeping his speed slower than it would normally be by keeping his hands against it but he's still too far up for hopping off a wall to be a good idea and then yeah, Peter, there's a gap there for the window, his hands catch hold of the other window ledge, yep, that hurt, oh man, he's going to have bruises on his hands later or something, play it off Parker.

"Two chocolate frogs, huh?" He smiles as he pulls himself up onto the first story window ledge, once again perching on it, this time crouching (spideystyle), finally turning back to face Tony with a toothy grin. "Thanks! Physics play a big part in this, so it's not that stupid."
