I found this posting...

My old man's a sailor
What do you think about that?
He wears a sailor's collar,
He wears a sailor's hat.
He wears a sailor's raincoat,
He wears a sailor's shoes,
And every Saturday evening,
He reads the Sailor's News. [or was that Sunday News?]

Repeat with "anthropologist," "refrigerator repairman," and "cotton pickin' finger lickin' chicken plucker" in place of "sailor" (including the last line).

In the second-last verse Tom gets frustrated and says "Playboy" instead of the Refrigerator Repairman's News. In the last verse he gets fed up and shouts out "My old man wears a BRA!" over and over until Dick calms him down.
