He's drunk in a bar, and he's telling someone (the bartender, or a fellow patron, perhaps) to call him a cab. Call a taxi to come and get him and take him home. And he'll give the driver a tip. The cab driver being the undertaker, taking the dead body (him, being so drunk, worn out, passed out, "dead") home.
In the second line, it's "stiff", not "still".
"That fool couldn't tell a real STIFF from a faker".
Just wanted to point out two mistakes...
In the first line, it is "cab", not "god".
"Call me a CAB and I'll tip the undertaker".

A stiff, meaning a corpse. A dead body.
Otherwise the lyrics are fine.
