This is going down in history as one of the worst pranks a son could pull on his mother.

The family of a 62-year-old nurse in Pomona, California says the woman's son tricked her into believing she won the $1.6 billion Powerball jackpot, according to KABC.

The woman’s boss, Shlomo Rechnitz, bought 18,000 tickets for his employees and residents at 80 nursing homes in California. The woman’s son reportedly sent her a picture of the “winning ticket,” telling her she won.

The woman’s employer called news media, and gave them a statement.

“Who would have thought the actual winner would be here at our facility,” said a spokesperson. “It couldn’t have happened to a nicer person.”

When they found out about the prank, Rechnitz called it despicable, according to KABC.

Rechnitz told the woman to have some fun with the situation. He said he would buy the family an all-expenses-paid vacation to anywhere they wish.
