Electrodes, dude. Electrodes. No sparks except on the bench equipment in the doctor's luh-BOR-a-torie.
And there is not a single more relevant avatar on the whole board. When you get drafted into the Atomic Engine Club you may wish you had the community support that Howie got at the time.
Look at his join date, his member number, and his post count. He's earned a little slack, and the right to a moment of sarcasm here and there. It's not a personal attack, and you don't need to take it as one and start hitting back. A nonsense answer is a humorous way of saying, "What the hell, I dunno!"
Criticising him for sarcasm in an oil thread??!!!??! Puh-LEASE!!!!!! That's what oil threads are FOR!!!!!!
As for taking him seriously, when he answers for real, his answer is gospel, like pointing that guy to the Gen-II handlebar thread. He reads the whole board, knows what he's seen, and can find it for somebody quite some time later.
