A guy in northern California recently told his roommate he hit the lottery for $10,000.
So the roommate stole the ticket, and swapped in a phony one he altered to look like the real one.
When the guy went to cash it, lottery officials told him it was fake.
Then the roommate showed up to cash the real ticket on Monday, and got arrested.
Here's the craziest part. They both thought the ticket was for $10,000 . . . but it was actually for $10 MILLION.
So now the guy's a millionaire, and the roommate is facing charges for grand theft.
