I dont even carry my social security card on me?

Whats with him carryin around the ticket!? That has to be the stupidest thing i have ever seen in a movie! Movie not that bad? But cmon, HIDE THE TICKET!!!!! I thought would carry for 1 day, 3 days go by anbd still carrying? Just a little flaw. And should have been caled "Lottery Friday" - cant even count how many exact same things are in each movie.
