haha the same thing kind of happened to me a couple of summers ago..
i was chillin on the couch for like 3 hrs playing socom 3 and i got up to piss and when i got to the bathroom i felt really light headed and so i started pissing and i blacked out mid piss and hit my head against the wall...
i have to get mine out next Thursday. the 2 on the bottom are impacted so they will b a little harder to heal and the 2 top are just routine extractions. so we will see.
