AA in limped pot

[mindless]

Playing 3/6 at UB, can't find the hand history. There's a 50/20 wacko OT who's been just bombing any limped pots, but calling people who raise in front of him, so I limp black AA with about 800 behind me. This sets off a chain of events with the next two people limping behind me, but instead of the button bombing it, he just calls. He probably was timing out and forgot to raise.

Anyway, the flop comes down 6 [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/spade.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img]

The SB (who had completed) leads out for pot. The BB calls. What's my action? What's my plan for the hand? SB has ~600, BB has me covered, I think the CO was short stacked and button was me covered.
