There are two types of families, those that make poop jokes, and those that don’t. My family is the former. “Anything smaller than a potato can be flushed down the toilet.” My dad says this with the absolute confidence of someone who’s seen (and done) everything. My sister is visiting from grad school, so the original four are all sitting around our living room watching TV. On screen a commercial is playing where a little boy flushes armfuls of plastic toys down a toilet. My sister and I have been debating whether or not some of the items would flush. “No way, that toy truck is just too big. It’ll stop up the toilet.” But after my dad’s statement it was settled. Anything smaller than a potato would flush down a toilet. I’ve never tested this hypothesis, but I know it for absolute truth.
