What Will You Do If....

You paid a visit to your friend in his house and you found out that he is taking his shower. You see a lottery ticket not scratched on his table. Since No one was there, you took it and scratched it and won $ 5000 with this joy in your heart, You put it in your pocket and you replaced it quickly with the ticket you yourself bought. When your friend has finished his shower, he took the replaced ticket, scratched it in front of you and he won $ 3 million.
Now my Question : what will you do ?
Waiting for a response

I'll tell him the one he scratched and won $3MD is mine while the one am holding with $5K is his own, if he doubt or plan otherwise I will drag him or her to amadioha shrine to swear if he is the owner of the card he's holding
