Lex has had a loose tooth for a little while now.
While brushing his teeth for bed tonight, Lex discovered that his tooth was really very wiggly and loose, so he decided to try to pull it out so that he could put it under his pillow for the tooth fairy as soon as possible.
Unfortunately, it wouldn't come out. Also, Lex isn't squeamish about blood. He had it dripping off of his chin, and onto his keyboard while he was playing Minecraft. Because obviously when you fail at pulling out your tooth, you get right back to what you were doing before that.
Fortunately, he was wearing a red shirt, because he kept wiping his bloody chin on his sleeve.
Maybe it will come out in time for the tooth fairy to visit tomorrow night.
