(The following is a cover letter I wrote in response to an ad for "Comedy Writer (female)---full time position includes benefits." Sadly by the time I wrote the cover letter, the ad had been removed. So someone else will be getting these benefits.)
Dear Potential 401(k) Providers--
I might be just what you're looking for. Not only am I a comedy writer, but I am also a girl. With menstruation and everything. How could this not work out?
As requested, I do have professional comedy writing experience in a variety of genres. In addition to writing for my own stand-up comedy career, I currently write political comedy for The Melting Pot Project, and formerly wrote comedic college admission videos for The U. I was even requested by the Oxygen Network to write a sitcom pilot, which I did. They chose not to read it, however, because they had just purchased a show for cats. FOR cats.
I am not making that up.
In lieu of the 10 jokes about the financial crisis that you requested, I'm linking to two comedic articles I've recently published about the financial crisis (now would be the time to write "terrible at following directions" on my evaluation.) You can read them here and here. However, if you'd rather read straight out set-up/punchline jokes, I've attached several below this cover letter. You can see other samples of my writing here, here, and here.
Best of luck with your work. I hope to get a chance to work with you in the future. But if this doesn't work out, I know where you can purchase a pretty cheap show for cats.
