The House reference is very welcome, and while I still find the whole "floating nipple" concept on the "not" side of funny, the doctor goes a long way toward pulling it off.
I'm also fond of Francis' excited expression in the third panel:
We don't see that often enough, and not just on Francis.
I do have a quibble, shocker I know, and it's with the script. In the last panel:
... we are treated to a cliched punchline, where the character maintains his dignity by explaining that it's not a bra, then contradicts himself and "totally" agrees to the original premise. That's so Friends, 1999. Plus, the "wtf" look on Francis' face is so tired -- I'd love it if he had gone back to smiling, knowing the shit Brent is likely to be getting.
Note: I appreciate that Francis is looking at the camera there, and it's exactly what I suggested a character do in a past strip (I'm not suggesting that's why Kurtz did it now), but so often emotion in PVP is nothing but a set of raised eyebrows; it's like a Botox convention around here. If there's a more expressive alternative, I say go for it.
I'm going to do something I've tried not to do for a while, as it has been suggested to me that it might be crossing the line, but in this case I can't help it. I'm going to suggest new dialogue (just for the last panel):
Doctor: Did I say bra? No. I said a sling. It's a clinical assistive device used in these types of injuries.
Francis: (shit-eating grin returns) So it's a bra.
Doctor: Yes it's a bra.
This sets up the humiliation, providing anticipation, and assumes we will be seeing Brent in his new bra. Because if we don't it will be a crime.
