Interrupt them when they are trying to annoy you. Then say "I'm sorry, sorry. What were you saying?" Repeat.
Agree with everything they say. It drive them crazy.
Ignore them. And sit and find somthing to read.that what my wife dose to me all the time lol
Copy everything they say. They'll get mad, which lets you know it worked.=]
Ignorance is much powerful than provocation.
Wait for them to finish their sentence, then say "WHAT?"
