[He lets out a peal of laughter once he's sufficiently squashed against the windowframe, shifts and wiggles and... just sort of ends up popping out in the right direction. There he goes -- there they go -- it's time to be a big heap on Watanuki's floor!

He's still grinning despite having knocked all his elbows on the window (or Watanuki?).]

Thanks for having me!

[He calls this out perfectly politely as though he really did walk through the door.]
