Recess! Funny Times Cartoon Playground
Set aside at least twenty minutes in your day to play on the Funny Times Cartoon Playground where you can create a one- or two-panel comic from preset characters (including a few from the White House), settings, props, and text ballons you fill in yourself. You can then save your masterpiece and allow it to be publicly viewed in the gallery, or keep it private and e-mail it to select recipients.
Just be sure to mind the bell and get back to class on time!
