If you're allowing "Uncle Sam" and "Mr Murphy" as being real, you've got to allow Wilbur and Farnell too, as there are real people with those names. Especially if the "MLLLER" one is a deliberate trick - that means you've got to be super-accurate.
I am truly sorry "Uncle Sam" is a genuine mistake however Mr Murphy was my middle school teacher and the other 3 names were made up by me. There is a chance that they are real people and I will do my best to correct these mistakes.
