can't keep my hands to myself

Before summoning Alexander the Great, Faustus warns the emperor to not touch him since they're immaterial spirits. After being summoned, Alexander the Great kills some dude and salutes the emperor. The Emperor was so amazed by the summoning, he attempts to touch Alexander even though Faustus told him not to and that it could cause him great harm. Sorta like Nemo when he didn't realize the dangers of touching the butt.
