When I get on a big yawn binge - yawn after yawn after yawn, yawns that bring tears to the eyes, and make me stretch my legs under the desk until my knees click, great big 10 second yawns that leave me shuddering with my gob wide open, yawns that make me do a Tarzan noise and little jets of saliva squirt onto my keyboard - when I get on a big yawn binge I also get a massive hard on.
Why is that?
What have yawns and boners got to do with each other?
