Photo of the Day: Poem Party Poster

You never know what you're going to see on the walls of the Big J. This was spotted at some point during the middle of the semester. I had to snap it with the cell phone before it disappeared.

However, it does pose a few questions:

To whom do I RSVP?
Where can I go to see who is attending?
Why are pants necessary?
Are only pants necessary?

WHAT DOES THE OSTRICH HAVE TO DO WITH IT?
