She Gets Double

There once was a man who traveled to a strange foreign country, and while he was there he found a strange old lamp of some sort. When he got home he polished off the lamp, and out came a genie. Then the genie said “I’ll give you three wishes, but on one condition, your mother in law gets twice as much as you wish.” 
So the man decided for his first wish that he wanted 1 billion dollars, so his mother in law (who lived across the street) got 2 billion dollars. For the man’s second wish he decided that he wanted to have a 200 room mansion, so his mother in law got a 400 room mansion. For the man’s last wish, he took a long time to think it out, and then he said to the genie, “I wish you choked me half to death.”
