This is the actual Hidden Mickey! This is a washcloth. He calls it his "Mickey" towel because he thinks the bubbles that I circled look like a (warped) Mickey shape!
The next 2 aren't really Hidden, but he found them before I really knew they were there.
If you are an ESPN fan, you're probably familiar with the show PTI: Pardon the Interruption. This is a favorite at our house. Every so often, if you look behind Tony Kornheiser's head you can find an angry Mickey. Cman ALWAYS points out Mickey while we are watching PTI!
The last one is part of the book Alexander and the Terrible, Horrible, No Good, Very Bad Day. At the end of the book Alexanders Mickey Mouse nightlight burns out. Before I even got to that line, Cman had already pointed out Mickey! Now we have to read this book every night so we can see the Mickey Mouse nightlight!
