Perhaps one of the greatest of God's creations, but at the same time the worst. It all depends on the circumstances. When the body goes into REM sleep, capillaries go into hyper vasodilation, and thus the penis becomes goes in one of the most intense and hardest erections a man can experience.
TEACHER: Tommy!? You're late again! Care to explain!?
TOMMY: You want the truth?
TOMMY: OK, here it goes. For the past few mornings, I've woken up with some gnarly morning wood
, and to waste something is a sin; so, I took full advantage of the situation each time.
DAN: Dude, what's up? You sick or something?
JAKE: No, man. I slept naked last night, and slept in this morning to the point where my mom came into my room and threw the sheets off of me. I had massive morning wood
, dude, and she saw it. AWKWARD!!!
