Peter said to his wife Claudia, "You will not believe what happened today! I bought an old lamp at the junkyard sale and guess what? I rubbed it and out came a genie!"

Peter replied, "Yes i did. I asked for your intelligence to be enhanced ten times."
Claudia said, "Oh! That's so sweet of you."
Peter retorted, "Yeah, but I forgot anything multiplied by zero remains zero."
