There's many ways to have fun with people who call your number asking for some person that doesn't live there. Usually they stop calling when you tell them they have the wrong number. Then there are the people who call back repeatedly despite the fact you told them wrong number.
Then we have another group who mis-dial your number when they try to order pizza, get a taxi, reserve a hotel room etc
When they call, tell them the person they're looking for is dead or in jail. You can also say they are chained up in the basement and the ritual is about to begin in 5 minutes. I remember a movie Danny DeVito played in, I think it was Used People. In the movie he got alot of wrong number calls and delivered a perfect line, She busy at the moment you see she got my dick in her mouth and I'll have her call you back after she's all done *click*.
As for business calls if you get someone calling a pizza place and they alway get your line pretend to be the pizza place.
"We have 2 large pizzas with any toppings and a bottle of soda for $7.99. It will ready in 20 minutes."
"Why don't you get your ass and pick your food. We ain't delivering it."
Alternately take their name, address, phone # and order. Then call the real pizza parlor (or a different one) using their info but change the toppings or add more stuff to their order. Call 2 or 3 other pizza shops in town and give an order for delivering. You are gonna have to use payphone or a pre-paid cell phone for stunt. They will wondering why all these restaurants are bringing them food when they only called one.
In a book called "Don't get Mad, get Even", this guy said he had a phone number very similar to a shop that sold fireplace accessories. He figured that he spent about $50 worth of his time every three months politely redirecting calls to the shop. So he sent them an explanatory letter and a bill. They ignored him or told him to take a hike or something. So he started telling all such callers to hurry in, as today was their annual unadvertised sale for regular customers, everything 50% off.
After a while the fireplace shop caught on, paid him is $50, and he went back to politely referring people to the correct number.
How do you deal with wrong number callers?
