TWBCoOP - Won a monster I should not have been in

Wow! I just took down a monster. Maniac raises 5x the big blind UTG (same thing he did for three hands in a row) so I raise to 1500 and he goes all-in. I figure this guy to be making a move so I call and it's my suited A-7 vs his A-J and I spike a 7 on the flop and it stands up to take down a monster double up.

Here's the hand history:
