A man was driving home from a party with his wife and son when he got pulled over at a DUI checkpoint.
The policeman gives the man a breathalyzer test. The machine beeps and the policeman asks the man to step out of the car.
“Bullshit!”, he exclaims in response. “I haven’t had a single drop! The machine is obviously broken, test it on my wife!”
The policeman reluctantly agrees as the man does not seem intoxicated. As the wife is blowing into the breathalyzer, it beeps again and shows that she is drunk as well.
“See? It doesn’t work! You can even test my 4-year-old son!”
So the 4-year-old kid takes the breathalyzer test and whaddaya know, it says he’s drunk as well. “As I said it’s broken, you should get it checked.”
The policeman is left puzzled, he apologizes and lets the man on his way.
As they start driving along again, the man turns to his wife and says:
“You see that? I told you it won’t hurt to give the kid a taste.”
