I know who Jon Lovitz is. I just don't get the connection with John Denver or Jon Bon Jovi, unless you're referring to the notion that all three of them should have been on Denver's plane when it went in the drink. Is that it? I thought maybe I'd missed another one of those celebrated classic celluloid creations that you keep posting up. 
  
BTW, what's pony-loaf? Is that a euphemism for horseshit? 
 It ain't been defined yet...
