This is What Happens When a Writer Can't Find Paper...

I used to have a notebook by my bed. Someone moved it last night. I had my pen...but no notebook. So of course inspiration chose the perfect moment to strike - a couple new stanzas for my picture book - and frankly I was too tired to go in search of paper. So I grabbed my pen and used the only available surface around (my furniture was too dark or I really think I would have just written on my dresser...or headboard :D ). I woke up with hands covered in ink.

Do you ever do this? What's the weirdest thing you've ever jotted a note on?
