From the movie "The Godfather":

Tessio: [to Hagen] Tell Mike it was only business. I always liked him. 
Tom Hagen: He understands that. 
Willi Cicci: [removing Tessio's gun] Excuse me, Sally. 
Tessio: Can you get me off the hook, Tom? For old times' sake? 
Tom Hagen: [shakes his head] Can't do it, Sally. 
[Hagen watches sadly as Tessio is led by Cicci and the others to a waiting car]
