Heck...I'm 31 years old and would try and steal a penguin myself. I dig those little birds. I rented the March of Penguins off of pay per view. Mr. TTB wasn't nearly as enthralled with it as I was.
I've gotten to go to the Shedd's Aquarium once...it was totally awesome. If ever in Chicago, it's a must see. Heck it was probably the thing I liked the best about Chicago (except maybe the bars staying open til 4:00 am!!)
