I think you are referring to the song 'IF You're going to Be Dumb" by Roger Alan Wade. The song also served as a soundtrack for the movie "Jacka$$". Here are the complete lyrics to the song for you:
"If your going to be dumb, you got to be tough
When you get knocked down you got to get back up,
I ain't the sharpest knife in the drawer but I know enough, to know,
If your going to be dumb, you got to be tough
Well, I drenched my brain with Rot-Gut whiskey
'Till all my pain was chicken fried
And I had dudes with badges frisk me
Teach me how to swallow pride
I took advice no fool would take
I got some habits I can't't shake
I ain't the sharpest knife in the drawer, but I know enough to know
If you're going to be dumb, you got to be tough
If you're going to be dumb, you got to be tough
When you get knocked down, you got to get back up
That's the way it is in life and love
If you're going to be dumb, you got to be tough
I've been up and down and down and out
I've been left and right and wrong
Yeah, I've walked the walk and I've run my mouth
I've been on the short end for too long
But if they gave medals for honky tonk wars
Hell, I'd put mine in my chest of drawers
With my irs bills and divorce papers and all that stuff
If you're going to be dumb, you got to be tough
If you're going to be dumb, you got to be tough
When you get knocked down, you got to get back up
I ain't the sharpest knife in the drawer, but I know enough to know
If you're going to be dumb, you got to be tough."
"If your going to be dumb, you got to be tough
When you get knocked down you got to get back up,
I ain't the sharpest knife in the drawer but I know enough, to know,
If your going to be dumb, you got to be tough
Well, I drenched my brain with Rot-Gut whiskey
'Till all my pain was chicken fried
And I had dudes with badges frisk me
Teach me how to swallow pride
I took advice no fool would take
I got some habits I can't't shake
I ain't the sharpest knife in the drawer, but I know enough to know
If you're going to be dumb, you got to be tough
If you're going to be dumb, you got to be tough
When you get knocked down, you got to get back up
That's the way it is in life and love
If you're going to be dumb, you got to be tough
I've been up and down and down and out
I've been left and right and wrong
Yeah, I've walked the walk and I've run my mouth
I've been on the short end for too long
But if they gave medals for honky tonk wars
Hell, I'd put mine in my chest of drawers
With my irs bills and divorce papers and all that stuff
If you're going to be dumb, you got to be tough
If you're going to be dumb, you got to be tough
When you get knocked down, you got to get back up
I ain't the sharpest knife in the drawer, but I know enough to know
If you're going to be dumb, you got to be tough."
