As a kid, I always wondered why there were beer bottles and cigarette butts in the shower. As an adult, I totally, totally get it.
I've since quit smoking, but I still love a cold beer in a searing hot shower. Especially my morning shower.
But yeah, I've opened a few of those ancient milk-bombs myself. It's right up there with the ****ty diaper that goes both up-the-back and out-the-legs. All you can do is hose everything off in the shower and it'll turn out fine. I love my kids, partly because they remind me that it's fun to go stomp in puddles and poke earthworms and get sand in my ears
