So this dude in my theatre class was doing a monologue about a man who murdered his parents and grandparents because they ruined his relationship and cut ties with his sister.

My sketchbook was right there in my lap, opened to a blank page.
I had a pencil in my hand.
Then my hand slipped.
And when I looked down, THAT thing appeared.

Uh..... I was originally gonna draw blood but laziness prevented that from happening.
