Oh! I get this!
So, person one introduces a scenario involving the world's worst something, such as the world's worst neighbor.
Person two then comes up with something the world's worst neighbor would say or do, not necessarily the identity of that person or object.
For world's worst neighbor, possible responses would be:
~"I hope you like Tibetan throat warbling, since that's the only kind of music that I'll play, and only at dawn while you're asleep!"
~*snip snip* "Oh, what am I doing to your hedges? I just thought that they'd be more interesting to look at if they were shaped like naked women, that's all."
~"Oh, don't mind me, I'm just going through your family photos. Nice photo of your husband, I think I'm keeping this..."
Or for an object, such as World's Worst Refrigerator:
~"I had a feeling that I might need to replace my refrigerator when I opened the door and saw that the eggs were already cooked."
~"My refrigerator is so bad, it doesn't run... It runs away
from me each time I try to get near!"
Mine were pretty bad examples, but I hope you all get the picture. (And don't forget to suggest a new "World's Worst" scenario once you've finished answering someone else's!)
I guess I'll start:
World's Worst Salesman (I can't wait to see what you guys come up with for this one!
