When I look at Pence's signature, I am reminded of Aleister Crowley's signature:

If you look at the "A" in "Aleister," it is very phallic -- two balls and an erect penis. No surprises here, as Aleister Crowley was into sex magick.

With this in mind, look at Pence's full signature. At the beginning of his name, I don't see an "8" so much, as a ball and penis. Also, the "R" for his middle initial is small, but then the following "P" in Pence is much larger, as though he's gotten an erection simply by writing his name. He either thinks very highly of himself or he's subconsciously thinking of sex/virility.
