Anything you can remember that is just ridiculous and un-needed...but everyone says to get one? 
We never used a play pen..but bought a new one with each kid!!!! 
LOL...MIL bought us one.  It's still in the new packaging in the closet.
I'm thinking its a "re-gift" for any up and coming baby showers <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
