How many bets with the nuts?

[obsidian]

I took my seat in a live 20/40 game and the very first hand I saw before I even came in I saw 2 guys go raise and reraise PF for around 15 bets. Of course both had AA but the fact that eventually one called was sort of surprising. I don't think it is rude at all to raise until you are all-in when you have the nuts. Thankfully, the dealer left the bets in front of them so it made choping easy when neither hit a flush.
