OK, I was really laughing at him. #2. In the morning he is impossible to get into the shower. He doesn't want to take it, and getting him to do so is quite a feat. Of course once in the shower, he does not want to get out. He only gets out when the hot water runs out.
My solution to this?
Everyone else takes their shower first so they have hot water, then when he has been in there long enough to get clean, I start doing laundry and/or dishes. Using hot water of course. This causes an immediate influx of cold water into the shower, resulting in a shocked scream and cessation of #2's shower.
Definitely one of the more guaranteed and entertaining ways to get him out of the shower.
