Hang on a minute John,
I don't see where you equate a one-off prank with doing "electrical work" later in life, we've all done something silly in our youth that we maybe weren't proud of.
Sure, YouTube and sites like that have a lot to answer for, but is it the fact that people can now show any idiotic thing they like these days in front of everyone else these days, where as before hand they would have been ignored like the simpletons that they are.
There was an article here on the Net some time back, when employers are looking for new staff, they go straight to places like Facebook and the like and find out what sort of a person you are and what comments you have made.
Better not link your FB account to any stupid pranks on YouTube, wether you did them or not.
Regardless of the qualifications you hold, even if you played up a bit at University,youngun's be afraid, very afraid!
