A "new"--to me, at least--take on an old theme:

"Only Daughter"

She was only a creditor's daughter, but she
allowed no advances.

She was only a taxi driver's daughter, but you auto
meter..

She was only a plumber's daughter, but she had
good connections.

She was only a surgeon's daughter, but oh, what
a cut-up.

She was only a photographer's daughter, but she
was well developed.

She was only the village belle, so I gave her a ring.

She was only a golfer's daughter, but her form was
perfect.

She was only the milkman's daughter, but she was
the cream of the crop.
