This is not funny, guys. Look at their respective article's pictures. It looks like someone took the Pratchett pic, rotated it, and changed the subject's outfit. Personally, I'm surprised that Dan Brown (the name that I'm currently using for Randi/Pratchett until I figure out what his real name is) didn't bother to dye his hair. 

Adding to the suspiciousness is the fact that both of them have had heart complications. Very CONVENIENT heart complications, which allows "Pratchett" and "Randi" to make public appearances in two different locations. 

If anyone can find me PROOF in the form of a real, unedited photograph that picture BOTH Randi and Pratchett IN THE SAME PLACE at the SAME TIME, then I will personally give you a million dollars as well as a million copies of the newest Pratchett novel  Thud.
