Statistically speaking, correlation is not necessarily causation. But, in the case of the extra fiber added to milk, and the Sunday night shart I got from Abby, I'd say it is. Keep in mind, Abby often runs around in only her underwear, "Brave" underwear at the current time. Her underwear are usually baggy, because she has no butt.
In cases like these, it's my usual course to throw away the offending underwear. Right out to the trash. But, these were new underwear, and Abby would notice they were missing. So, I cleaned off what I could in the bathroom, then went outside to squirt them down with the high-powered hose nozzle, before I ran them through the wash. Due to back-splash, it was not a good idea.
It reminded me of the time I was working as a landscape maintenance worker the summer after my freshman year of BYU. Some of our jobs included 11 churches in the Provo/Orem area. I was at one of the churches, using a gas-powered weed whip, and whipped right through a pile of fresh dog poop. It splattered my glasses and face, and sent me running to a house next door that had sprinklers going. I knelt down at the sprinkler, and scrubbed my entire head off, while gagging.
I'm so glad my mouth was shut.
