The funniest (for me) were:
1. I can see your point, but I still think you're full of it.And this one holds a special place for me since (although maybe I shouldn't admit it) I've used it before:
3. How about never? Is never good for you?
4. I see you've set aside this special time to humiliate yourself in public.
6. I'll try being nicer if you'll try being smarter.
10. Ahhh...I see the screw-up fairy has visited us again...
14. I'm already visualizing the duct tape over your mouth.
20. I'm not being rude. You're just insignificant.
23. And your crybaby whiny opinion would be...?
27. Sarcasm is just one more service we offer.
28. If I throw a stick, will you leave?
8. I don't work here. I'm a consultant.Thanks to Paul Jané for the tip.
