After a great deal of careful consideration and introverted speculation, I have deduced that Inigo Montoya is equivalent to Pumbaa the Warthog. Why? Both Mandy Patinkin (Inigo) and Ernie Sabella (movie Pumbaa) have played Sancho in Man of La Mancha. Listen to some of Sancho's songs in the Placido Domingo version and chortle merrily at Mandy singing, keeping in mind at all times that this is Inigo singing, too.

Har.

I'm back, by the way. XD
