I've had a lot of friends do this (male friends) who keep their phones in their pockets. So I've heard this alot...
Another recent one was my nephew who walked in to the sitting room to tell his dad... Uh oh daddy... I've washed it... on getting up to go and see what is was the toddler had washed - he discovered it was his brand new mobile phone, which was at the bottom of the bowl all soapy.
The little blighter had dragged the kitchen stool over to the sink, and climbed up and washed the phone - along with other unsuitable things.
