Narrative:

During the deplaning of the passengers; the nosewheel of the aircraft rose approximately two to three feet above the ramp surface for a few seconds and abruptly returned to the ramp. The auto leveler raised the jetway as the aircraft tipped and when the nose wheel returned to the ramp surface; the main cabin entry door contacted the jet bridge. Deplaning was halted and the jet bridge was lowered. The remaining passengers exited the aircraft. Maintenance was notified and a logbook entry was made. The first officer was standing in the jetway; and I was doing the post flight inspection and witnessed the event. Both the forward and aft cargo bins had been emptied and the doors were closed. Both the potable water and lavatories were being serviced at the time. The lav truck was nearby but did not contact the aircraft. At no point did the tail contact the ramp surface. The fuel load at the gate was 5000 pounds and the total passenger count was 160. The event was estimated to have occurred with passengers in the last 12-15 rows of the aircraft. After a discussion with the cabin crew; there were a few passengers who took an unusually long time to gather their luggage; prolonging the amount of time with passengers in the aft section of the aircraft.

Title: B737-800 Captain reported that during deplaning the aircraft nose wheel rose two to three feet in the air and then came back down presumably because of the number of passengers still in the rear part of the aircraft.
