Drunk man bumps violently into a stranger on the street. The later slaps him on the face.
The drunk:
“Ha! I am back home already!?”

Recovering alcoholic decided to test the strength of his will. Passing by the liquor shop he said to himself:
“I am not going in!”
After 10 meters:
“Making the test harder – I will go in, but will not buy …!”
He entered the shop, looking at his favourite brandy:
“Making the test even harder – will buy, but will not drink!”
So he bought the brandy, went home and put the bottle on the table:
“A new test – will open the bottle, but will not drink!”
He opened the bottle :
“Last test – will drink, but not swallow!”
And he drank and swallowed:
“Hey …, now that’s a willpower! I didn’t want to drink, but I was persistent and won!”
