Tell your best work related screw up story!

I'll go first.

A little background first. We work on heavy trucks, tractor trailers, box trucks, conveyor trucks, bucket trucks, ladder trucks and by far our most frequently repaired trucks are the drywall crane trucks. These things are big 6 wheel drive trucks with cranes that can extend up to 7 stories with hydraulically operated fork assemblies (kind of like a fork lift) on the end that hold 3000 pounds of drywall on them. Well today we changed a couple joystick controls on one and one of the controls was bad, or the installer hooked it up wrong. As soon as it was touched the crane swung wildly to the right embedding the fork assembly into the cab and windshield of a 2004 Freightliner tractor. The really bad part is the Freightliner belongs to the company that my wife works for. I got us the account so I feel really bad.

We will of course take care of all the damage and even rent a tractor for them while theirs is being repaired but man am I dreading this conversation. I haven't even told my wife yet. This is about $4500 in damage plus a lease truck to the tune of about $1000 per week, depending on the mileage.

And today was my one year anniversary.
