That was probably the option with the $100 shipping problem.
EDIT: Actually, what am I thinking? Of course he knows a seamstress, he knows a friggin' costumer, and she's in your area -- my sister. Let me know Al, this is right up her alley, it's only a matter of her availability, I'd be happy to put you in touch with her. You'd have to pay her though, this is what she does for a living, but I'm sure you can work something out.
EDIT #2: Sister asks -- because she actually does have some work right now -- is it for the 31st proper, or is there a party beforehand, I.E. Saturday? I.E. what's the actual deadline?
EDIT #3: So I'm guessing from "shipping...in time" comment, that it's not for the 31st proper, it's for Friday or Saturday, neh? I say just dew it. You only get to be Dr. Horrible once.
Actually, you get to be Dr. Horrible for the rest of your life if you do it right.
EDIT the last: confirmed -- you're not going to pay any less paying for my sister's services (but...it'll be better). I say you can do one of two things -- choke it and pay, but take it out of your son's allowance, since it's his fault for waiting until the last minute, or check out the local medical supply stores.
I'm a gonna get one of those for everyday wear. I'll see if it comes in pre-blood-splattered, maybe it'll be cheaper. I'd look dapper in a mandarin style cloak.
