I picked this up for my eight year old son the other day, and he didn't quit talking about it for two days. Two days of random facts about pee.
"Hey, Mom! Did you know that the first gas masks were made out of cloth that had been soaked in pee?! Yeah! They just tied it around their faces! Ewwww!"
"Hey, Mom! Did you know that people used to put pee in their ears to cure earaches?! Ewwww!"
"Hey, Mom! Did you know lobsters pee in each others' faces?!" Ewwww!"
So, yeah, he loved it.
I ended up reading it while I was sitting in the car line waiting to pick the kids up, and you know what? It was pretty cool.
Unfortunately, now I have a bunch of random facts about pee stuck in my brain.
