There is a reason I don't take signs like this to work:
Consider the actual conversation I had with a coworker today.
Coworker: Becky, these headers are supposed to have nuts in them.
Me: You'll have to take them back to tubing [department}.
Me: You'll have to take them back to tubing so they can drill a hole in them for the nut.
Me: You'll have to take them back to tubing so they can put the nut in them.
Me: Go show them to [group leader] Fernando.
So, yeah, if I'd taken that sign in to work, I'm pretty sure I'd have had to spend all day explaining what that little house was.
