What are the mice in my head drinking...

As I walked to the bathroom today, I looked down at my freshly doubled-knotted shoelaces and instantly thought: "Oh no! I've tied my shoes too tight—now how will I go to the bathroom?" 

My second thought was: "Why did I just think that?"  Was I planning on taking off my pants? Did I get confused and think that one went to the bathroom with their feet? Was I channeling Britney Spears right before she walks into a gas station restroom?
