You know what'll put a damper on your day? Getting a giant splinter jammed in to your heel. I can't say whether or not prior knowledge that it is going to happen helps at all. But I can tell you the a surprise stabbing sucks. A lot. The following need to dig said piece of wood out of the foot with a pin also sucks. A lot. And finally, the continued pain throughout the day and night - you guessed it - sucks. A lot.
All in all, it's not something I could, in good conscience, suggest you try. Which may or may not have something to do with the throbbing pain in my heel that spreads out to my toes and up to my knee.
Let me conclude by saying "ow".
