I would like to extend to you an invitation to the pants party.

Our reading
An editorial interpretation.
A stiff, formal invitation becomes a clumsy sexual proposition when the event is called a pants party. The comic mismatch lies between the elaborate courtesy of the opening and the blunt innuendo at its end. The wording makes a suggestive approach sound like an official invitation.
