Genital

There was a young man named Rex,

With exceedingly small organs of sex,

So in charge with exposure,

He replied, with composure,

De minimis non curat lex.

There was a young girl from Hong Kong,

Whose cervical cap was a gong.

She said with a yell,

As a shot rang her bell,

"I'll give you a ding for a dong!"

A mathemathician named Hall,

Had a hexahedronical ball,

The cube of its weight,

Times his pecker, plus eight,

Is his phone number - give him a call!
