Relief

The drunken wino was stumbling down the street with one foot on the curb and one foot in the gutter.
A cop pulled up and said :
- I've got to take you in, sir. You're obviously drunk.
The wasted wino asked :
- Officer, are you absolutely sure I'm drunk ?
- Yeah, buddy, I'm sure, said the cop. Let's go.
Obviously relieved, the wino said :
- That's a relief... I thought I was a cripple.
