Just after graduating high school I was working the closing shift at a gas station, occasionally, one of the daytime employees would come to do this or that. One night one of the guys brought in his bedless 56 ford pickup and said he needed to put it up on the lift. About ten minutes later, I hear yelling and screaming in the service bay, I run in, the lift is all the way up, and he's standing under the front, arms over his head holding his truck up on the lift. He had set the pads like normal, but with no bed, the truck was seriously front heavy and it was ass in the air balancing right on the front edge of the lift arms. I ran over, lowered the lift and laughed a lot. That was a fun job, and learned a lot too. U-joint went bad, the boss says "it's easy, put it on the lift, drop the drive line, hammer out the old ones, tap the new ones in gently and put it back together". Easy enough, got it on the lift, undid the back clamps and gently pulled the yoke out and got a face full of ATF. Managed to get the yoke back in before I lost very much, but I was sorta hippified back then, long hair, beard, and such..and the boss says "oh yeah, when you pull the yoke, we have this cap you slide into the hole so the oil doesn't leak out.."
