Do you think it would do anything to call him on just that? Next time he gets all mushy, remind him of the venom and ask why the difference now? Would probably just bring him back to mad, though........

Could this idea be reversed? Remind him of the politeness when he starts to spew venom? I guess that goes back to hanging up if he can't talk to you respectfully.

Do you remember the scene when Tom Cruise keeps getting hung up on by the pimp in Risky Business? That's what I was thinking...
