From oral tradition:

Keep on truckin', mama, says truckin' my blues away.
Keep on truckin', mama, trucking all the goshdarned day
You cando what you do, say what you say
But when it comes down to doing it, there's only one way
Keep on truckin', mama, says truckin' my blues away.

My man's a deep sea diver, he goes down so long (2x)
He goes down like a good man oughter
When he comes around it ain't with water
My man's a deep sea diver, he goes down so long.

Keep that black snake off me, it's cold and clammy to the touch (2x)
Mama, mama, don't you realize
Black snake b'longs between your thighs
Keep that black snake off me, it's cold and clammy to the touch

Now what's that smells like fishes? Tell you if you really want to know (2x)
It ain't sardines, don't come in a can
It's what every woman wants from every man
Now what's that smells like fishes? Tell you if you really want to know

You can lick it if you like but don't you dare bite it, even if you want it bad (2c)
With a popcorn man you got to throw him around
But if you want my nuts don't put me down
You can lick it if you like but don't you dare bite it, even if you want it bad
