At least from my viewpoint, this was funny. We were carpeting a clinic. Had 2 trashcans and a piece of tape blocking the entrance to a hall. I heard somone yell and a doctor in a suit, had stepped around the cans and under the tape and fell flat on his back in the glue. He looked up and asked "what do I do now?" My partner said, "first thing, get the hell out of my glue."
