I licked a 9 volt from the beeping smoke detector the other day to see if it was dead. Nobody was around to impress and it wasn't for fun, just wanted a quick result.
Would probably shock myself if stuck alone for 15 mins too. Heck, I find those shocking handle games to be hilarious fun.
Note: have ADHD which may or may not be related since I keep forgetting how much getting shocked hurts. Burns leave a mark and are more memorable so I wouldn't touch anything hot for fun.
