"Like I tell all my patients, you've simply got to say no to strangulation"—Dr. Gregory House
Seriously, don't do this at home,
(("you may like, become insane retard from brain damage" or something, not saying this in 100%-accuracy so let's not argue,))
my point is that strangulation and oxygen-starvation can really lead to regretful conditions in health.
Sorry about the sudden over-care to just say don't do this at home, haha.
