Does anybody else think it's stupid that Harry named his secret little delinquent group Dumbledore's Army? I mean that gave him absolutely no deniability!
Correct me if Im wrong, but at least they had been calling themselves the D.A. in public. That gives them some room to deny the shit out of whatever allegations they're facing.
Marietta Edgecombe: It's called Dumbledore's Army, Prefessor Umbridge.
Neville: Actually professor, we're the Dog Appreciators. We all agree dogs are not appreciatated enough.
Luna: I thought we were studying to be Districy Attorneys?
Ron: I'd heard we were the Defence Association.
Gred and Forge: We both could of sworn we were a smaller branch of the wizard's Dental Association.
Ginny: Wasn't this Delinquent Anonymous?
Harry: We're -
Hermione: If you hadn't gathered enough already professor, we're the Dumbasses.
Either this or they could just out Karen Umbridge.
Or this...
Harry: Just wait till my father hears about this!
Umbridge: Your father is dead Harry.
Harry: Well excuse me, you looked like you'd be joining him soon.
