I didn't even have to take a test to receive that toilet paper diploma.
I don't know why Mike hangs that toilet paper diploma in his office. It's not recognized by anyone outside this office, and by almost noone inside this office.
A con artist. A person that looks for people down on their luck, offers them help, and then seeks to control them. Much like a paper tiger appears scary at first but is merely an illusion of ferocity, a paper angel appears helpful at first, but is actually an illusion of assistance. A paper angel will lie and abuse it's victim to coerce control over them.
