I had the hardest time keeping a straight face! After several kids said they had spotted a Lirpaloof in one of our playground trees, I brought them inside and asked them to help me spell Lirpaloof backwards. It took a little bit, but finally one of the kids had a light bulb moment and figured out that the Lirpaloof was a prank.
After some laughter, I told the kids that I was sorry if any of them felt bad and that I would make it up to them after recess with treats that I brought. I told them I brought brown Es, but of course they all thought I said brownies. It took awhile for them to get it, but when they all finally did we all had a good laugh. Since they were all such great sports, I passed out brownies (the real thing!) for all the kids to enjoy.
