Lottery at a gas station

Advertising at the gas station:
“He who puts on a full lighthouse will be able to participate in the lottery! Prize – free sex!
” Two old men approach, add a full lighthouse and go to pay. Of course, the elders ask if they can participate in the lottery. The owner of the petrol station explains that the rules are very simple – he imagines a number from one to ten, the one who remembers has won.
One of the oldest:
– Seven!
Host:
– No, I imagined the number two, try next time… Not a week goes by when the elders are here again.
– Three!
– Unfortunately, I imagined five, maybe next time you will do better…
The old men get in the car and one of them says: – Its a lot of suspicion. Maybe he’s just a fraudster?
The other eagerly answers:
– No, you what! My wife has already won twice!
