UNCLE TONY WAS THE ULTIMATE CREEP!
(Spoiler alert)
I can't believe no one has commented on this. Tony would have chopped off his right arm for the chance to hump his best friend's wife. His flirtations were so over the top and inappropriate. Even when he interacted with Jane (the oldest daughter), it seemed extremely inappropriate. Even more amazing is the fact that the movie tries to pass Tony off as this lovable funny guy when it's obvious that he's nothing more than a narcissistic cad. Tony was probably royally pissed when he found out his best friend was still alive.
