Congratulations were showered on Kaplan. His number 49 had won the top prize in the lottery.
"Say Kaplan," asked Goldstein, "how did you happen to pick number 99?"
"I saw it in a dream. Six sevens appeared and danced before my eyes. Six times seven is 49, and that's all there was to it."
"But six times seven is 42 not 49."
"Hah? . . . All right, so you be the mathematician!"
