Pictures, Cryptic Bullshit

So, pictures first.



Pictures.
I woke up this morning a bit later than usual, went to sleep later than usual though, splitting headache, and cryptic shit all over my right arm.

The stuff on the inside of my arm might be a little hard to read. It says
"Nemo"
then there's a tally count of six
then an Alice in Wonderland quote
"How is a Raven like a writing desk?
On the outside of the forearm, we have "Tell the truth"
And somehow, on my elbow has been written "Stop lying"
All of the Os have been crossed through into operator symbols.
It was written in permanent marker.
The big question is "who done it?"

I'm betting the featherbrain.
