I don't know if this has already been discussed, but does anyone have 
any theories why Mundungus was banned from the Hog's Head 20 years
ago? (OotP) That's about the time that Voldemort was on the rise and 
possibly about the time that the prophecy was made in the Hog's Head
(correct me if I'm wrong).
And if it is Aberforth that's the barman at the Hog's Head (and 
therefore the one that banned Mundungus), do you think there's a rift 
between Aberforth and Dumbledore?
Or maybe Mundungus was banned because he's the one that snitched on 
Aberforth for performing inappropriate charms on a goat!
