Raspberry + Finger + Marker = Silliness at Work

Let me just start this by saying, one of my favorite fruits is raspberries.  I was having a some delicious raspberries as a mid-morning snack yesterday.  I decided to stick one on my finger, and say "look, my finger has a hat."  My co-worker suggested that my finger needed a face.  This is what happened.

One would say I had too much time on my hands.  One friend told me I needed to name him and suggested Raspbert.  The other said I needed to start a YouTube channel.  The Adventures of Raspbert.

What's the silliest thing you have done at work?
