Diaper of Champions

After washing a load of laundry this morning, I found this as I was putting all the clothes into the dryer: a water-logged diaper. Unfortunately, this is not the first time I have washed a diaper/pull-up. This is however the first time I weighed it because clearly, I had nothing better to do at the moment. Coming in at 2.5 lbs. this diaper is absolutely impressive. I don't know if it was clean or dirty going in, but it's now brand new with the exception of the bloating.
How did said diaper get into the washing machine you ask? My guess is Baby Jaws. He is known to throw things into the laundry basket. I've washed toys, diapers and even food.

How do I not find these things before they end up in the washing machine you ask? I am not a laundry aficionado. I don't even separate colors from whites half the time. If by chance I have a little bit of laundry, I just dump it all in at once. I've found it's easier for me. I've seen things in the laundry basket I fear to touch and dumping the entire basket alleviates that fear.
This is definitely not my mother's or grandmother's way of doing laundry, but it works for me even with finding the occasional added bonus.
