Stupidest "technical" advise I've heard lately

So how many of us still run amp meters on our cars instead of volt meters.

Heard this one in a conversation at a parts store, which way do alternators turn in Australia? They were serious, customer and parts counter monkey discussion. Couldn't stand to hear two morons think they knew the answer. Who the F**k cares I'm in Houston.

Oh and then there's the guy who wants to know why I need a new battery since it checks out dead at OReillys, just jump it off he says.
