Has anyone ever laid down the made nuts? And would you push this draw?

[Tankker]

I had a hand the other day, where I raised preflop with AKcTQs and got 5 callers in a live 2-5 game. My image is slightly loose preflop raises and tight with my big bets I believe. Effective stacks are $450 since he just bought in.

I get 5 callers
Flop: Pot $65

3 checks, I pot, old man who plays pretty much the same as me but is VERY VERY rich, repots, all fold and I push here.

Anyone NOT push here? I was 100% sure that he had QJ and since he didnt repot PF I think it rules out KKQJ which is just about all I am behind.

This brings me back to my other question of does anyone ever fold a made nuts hand? and could you propose a situation where it could happen? I imagine that theres no way it could happen for less then 2-3 buyins.
