Did you know that you could “tattoo” a banana with a safety pin or other sharp object? This was news to me (and yes, I live under a rock). So when I saw this post I decided to try it myself. And waddayaknow?! I wish I could have surprised David with this in his lunch, but unfortunately I did it on a Thursday night, and he works from home on Fridays. Oh well! I have a feeling this might be a staple messaging service for when the kids get packed school lunches someday.
