David 'Dave' Seville: Now I know cutting-edge scientific research isn't the cleanest topic in the world, but this is ridiculous!
[to Alvin, Simon and Theodore]
David 'Dave' Seville: I want you all to clean up this room.
Alvin Seville: Aw, Dave. Now?
David 'Dave' Seville: Now. I invited the new neighbors over, and I don't want them to think we live in an erector set.
[walks out of the room]
David 'Dave' Seville: I'm going shopping and I expect this place to be spic and span when I come back.
[slams the bedroom door as he leaves]
Alvin Seville: [sarcastically] Nice going, Simon.
