Neville Longbottom: [walking with McGonagall and Seamus] Let me get this straight, Professor. [grabs her arm] You're actually giving us permission to do this? 
Minerva McGonagall: [rolls her eyes] That is correct, Longbottom.
Neville Longbottom: [stops her] To blow it up? [exited] Boom?
Minerva McGonagall: [yells] Boom!
Neville Longbottom: [laughing] Wicked. [then turns serious, Seamus starts laughing] But how on earth are we gonna do that?
Minerva McGonagall: [sarcastically] Why don't you confer with Mr. Finnigan? [Seamus stops laughing] As I recall, he has a particular proclivity for pyrotechnics.
Seamus Finnigan: [nodding] I can bring her down.
Minerva McGonagall: [excited] That's the spirit. [shooing them away] Off you go.
