When you're in a ton of pain, pain killers can be a real godsend. Just ask this Scottish guy with a cracked up ankle!  
This man ended up in the ER with a broken ankle and was given the news that he'd need surgery, but that the ankle would need to be reset first.  That is a pretty painful process, so the doctor told him that they'd give him a dose of strong pain killer ketamine to help ease the pain a bit.  And it sure took him on a wild ride!

Within seconds of receiving the drug, our busted-ankle buddy was quickly on cloud nine, yelling, laughing and carrying on, but he sure seemed like he was enjoying himself!

Not bad, considering he was going through a very painful ankle reset while this was all going on!
