Baldurs gate 2, funniest party?

So I'm starting a new game, not looking to powergame but to have as much fun as possible and I was wondering what's the Funniest party you could have.
I'm thinking:
Me (half-elf Cleric/ranger)
Jan
Minsc

Again, wat

The less AC you have the harder it is for the enemy to hit you as they roll for THAC0 (to hit armor class 0) how is that hard to get?

Say you have THAC0 of 3 the you would hit an enemy with ac 0 on  a 3,4,5,6 roll with a hitdice. If the enemy has AC -1 and you have Thac0 3 you would hit on 4,5,6 and so on.
