A salesman walking along the beach found a bottle.
When he rubbed it, lo and behold, a genie appeared.
"I will grant you three wishes," announced the genie.
"But since Satan still hates me, for every wish you make, your rival gets the wish as well -
- only double." The salesman thought about this for a while.
"For my first wish, I would like ten million dollars," he announced.
Instantly the genie gave him a Swiss bank account number and assured the man that $10,000,000 had been deposited.
"But your rival has just received $20,000,000," the genie said.
"I've always wanted a Ferrari," the salesman said.
Instantly a Ferrari appeared.
"But your rival has just received two Ferraris," the genie said.
"And what is your last wish?
" "Well," said the salesman, "I've always wanted to donate a kidney for transplant."
