Talk about a birthday surprise! A D.C. man won $5 million from a scratch-off lottery ticket in Maryland last week, and the matching number that netted him the prize happened to be his age.

Maurice Williams, a school bus driver in D.C., claimed the first top prize on a $5,000,000 LUXE scratch-off. He had used his $50 winnings from a previous LUXE scratch-off ticket to buy a new one the next day.

In a release from the Maryland Lottery, Williams said he didn’t know he had won until he scanned the ticket: “It’s crazy because the matching number was 59 and I just turned 59 the other day.”

Williams said he sat in shock for a while before calling his mother.

He said he plans to buy his mother a house with the winnings and then save up.

Two more top prizes from the scratch-off have yet to be claimed, the Maryland Lottery said, as well as nine $200,000 prizes, 10 $50,000 prizes and thousands of prizes ranging from $50 to $10,000.
