Signs, signs, everywhere are signs

One of the toilets got clogged. Yuck. I was in the middle of making dinner when the kids told me about it. I wasn't about to fix it right then, so the girls took it upon themselves to put up warning signs. Elisa put up the expected sign: "Out of order." Later on, when I finally had a chance to fix the problem, I saw that Rachel had also put up a sign that was supposed to read: "Who did it? Rachel did it! Meow!" But Rachel is in kindergarten and sounded out the words she didn't know. Plus, she still mixes up her b's and d's. Her sign actually read: "ho bib it? Rachel bib it! meow!" Have I mentioned that Rachel thinks of herself as a cat?
