Side effects of going balls through the walls are: excessive dehydration, headache, fever, fatigue, and most likely death. Those who survive going balls through the walls are either really lucky, or the absolute quintessence of badassary.

I tried going as balls through the walls as Mennell, but then I ended up in the hospital. I'm lucky to be alive.
