Not me - but the kid down the street had the knack. He was always tinkering and building stuff. He once completely ruined his dad's extra television that was working fine but being stored in the garage for use in some property they owned. He took the thing apart to see the inside. He asked if i could help him put it back together before his dad found it, but i didn't have the knack.

He once built a small, gas powered model plane from a kit. He managed to introduce gasoline into the tail section, started the engine and caught the tail on fire and released the aircraft ...it flew over their 6-7 foot fence and up into the air and over the neighbors house. It came down in a ball of fire and caught the neighbors fence on fire. He also had a knack for getting into trouble

You know you were asking for it:

Had the knack but lost it

You know I had to respond.

I have the complete opposite of the knack
All I have to do is press the on button and #%&*$# breaks.

Heh heh, that Cheech and Chong scene makes me think that it might have influenced Beavis and Butthead.

LOL I do.

Don't have the full-on "knack", but maybe "ack". Taking apart is fun and easy. Putting back together and working properly again is kind of 50/50.

I was making a decent chunk of change on the side fixing iPhones, then some Chinese kid cut my price by like 50% and that was that. I mean I was $20 cheaper than any of the cell phone stores around ASU, but this kid was dirt cheap. I bet his parts were cheap replacement parts though, I used quality glass and LCDs.
