Government worker

Kowalski worked for the Department of Transportation. One day he woke up ill, with a touch of laryngitis-but-being a dedicated employee he went to work. The boss felt rather sorry for him and didn’t want him to do any physical labour-as they were repairing a part of the freeway.
“Kowalski” he says “why don’t you go down the road and tell people to slow down going through the construction”

Kowalski is glad for the easy day: He stops the first vehicle:

“Sir” he whispers, his throat feeling worse “please slow down, there’s a Government crew up ahead”

“Okay” the guy whispers back “I’ll try not to wake them”
