One time my MIL volunteered to help me and DH paint our house. We were working on the last area, our front porch. We didn't have the porch floor down, just sheets of plywood over the floor joists so we could (carefully) walk around. MIL was sitting on the plywood painting, and my husband kept warning her to stay in the middle because the plywood might tip if she got too close to the edge. No sooner had he said it, the sheet of plywood flipped up, and MIL was under the porch. The bucket of paint she had was spilling everywhere and she called DH to grab it. He ran over, slid in the paint and went flying off the porch! No one was hurt and we all had a good laugh...and I stayed out of the mess because I was on the ladder caulking the windows! :-D
