Q: How many lawyers does it take to change a light bulb?

[HerrNY]

A: Whereas the party of the first part, also known as "Lawyer", and
the party of the second part, also known as "Light Bulb", do hereby
and forthwith agree to a transaction wherein the party of the second
part shall be removed from the current position as a result of failure
to perform previously agreed upon duties, i.e., the lighting,
elucidation, and otherwise illumination of the area ranging from the
front (north) door, through the entryway, terminating at an area just
inside the primary living area, demarcated by the beginning of the
carpet, any spillover illumination being at the option of the party of
the second part and not required by the aforementioned agreement
between the parties.
The aforementioned removal transaction shall include, but not be
limited to, the following. The party of the first part shall, with or
without elevation at his option, by means of a chair, stepstool,
ladder or any other means of elevation, grasp the party of the second
part and rotate the party of the second part in a counter-clockwise
direction, this point being tendered non-negotiable. Upon reaching a
point where the party of the second part becomes fully detached from
the receptacle, the party of the first part shall have the option of
disposing of the party of the second part in a manner consistent with
all relevant and applicable local, state and federal statutes. Once
separation and disposal have been achieved, the party of the first
part shall have the option of beginning installation. Aforesaid
installation shall occur in a manner consistent with the reverse of
the procedures described in step one of this self-same document, being
careful to note that the rotation should occur in a clockwise
direction, this point also being non-negotiable. The above described
steps may be performed, at the option of the party of the first part,
by any or all agents authorized by him, the objective being to produce
the most possible revenue for the Partnership.

Давай друг път линка откъдето си го копирал, иначе си е плагиатство. Можеше да смениш едно две неща и да се хване някой.
