My brother is a dick.
He usually goes to sleep before me since he needs to go to work quite early. However, the other night he decided that he was going to leave me a surprise before he went to sleep.
He slipped a baseball into my sheets... nicely hidden.
I went to sleep that night without noticing the baseball.
As the night went on, I must have moved and rolled onto it or something. I woke up sleeping directly on the damn baseball.
Stupid Tim... my back still hurts from it.
