[Papyrus flinches a little at the change in tone, even if it was delivering another pun. He's only now realizing what an improvement the egging on of fashion ideas is, over the pained horror that's been ongoing since the end of the drive.]

It's not much better, with its one benefit that Papyrus can see if anything gets worse. The helicopter takes to the air almost before he directs it to, the better to perch up somewhere to keep watch. For Papyrus's part, he grimaces with the discomfort of being earnest.]

I'm... I was using you, as an excuse. For dragging my feet. [What feet, one might ask, which makes it a pun with layers. Matching the hair pun, trying to pull things back to levity.] If I didn't need, to check my neck... [His voice is returning, but is it repairing correctly?]
