Aw man, I used to get prank calls at the pet supply store I used to work at. My absolute favorite one was this:
PC (prank caller)
Me: Thank you for calling (company) this is Shabo how may I help you?
PC: Yeah, hi, I bought a dog from you guys a couple weeks ago?
Me: A what?
PC: A dog.
Me: No you didn't.
Me: Were you maybe thinking of (local competitor that does sell dogs)?
PC: No. This is (company), right?
PC: Yeah, I bought a dog from you.
Me: No you didn't. We don't sell dogs.
PC: Alright then, I bought a cat.
Me: (starting to laugh a little) No you didn't!
PC: Why not?!
Me: Because we don't sell them either *lol*
PC: Fine. I bought a bird.
Me: Ok, so you might have bought a bird, what about it?
(at this point, PC gave the punch line, I heard drums in the background, and he hung up. To this day, I wish that I had heard what the punch line was. It had to have been good for him to keep trying the joke.)
The other prank call that I still remember was really stupid.
PC: Yeah, I have these birds and I wanted to get some food for them.
Me: Ok, what kind of birds do you have?
PC: Well, they live outside.
Me: Oh, so you need wild birdseed. If you come on down, we can...
PC: No! I can't feed them that! They attack my dogs and my horses, I don't want to make them any wilder than they are!
Me: (not in the least bit surprised at this guy's stupidity)Sir, the food won't make them wild. It's called "wild birdseed" because it's made for birds that are not tame.
PC: No, you don't understand. I can't make them any wilder! They terrorize my horses and dogs, and sometimes they even attack me!
That call went on for about 5 more minutes, and I seriously was starting to think the guys was mentally retarded or something from the way he was talking, until I heard laughing in the background and clued in that it was just a prank. I think I ended up hanging up on him, telling him to come in if he wanted more help.
Two weeks later, I get the *same exact call*. I ended up just putting him on hold and letting it go until it disconnected. He called back, and promptly got put on hold again. He called back a third time, but didn't wait to get disconnected and hung up.
There were many many other prank calls that I got. I was fortunate enough to have cool managers that told us to hang up on them.
